As far as athletes go, we runners aren’t usually known for our fair-weather tendencies. We still get out there when the raindrops start to fall — and when the going gets tough, we keep going. While splashing through some puddles or weathering a drizzle on a short run may not be a big deal, extended wet weather on a long run can range from simply uncomfortable to downright dangerous in cooler temperatures. A solid rain jacket is a must for anyone looking to train through all types of weather conditions.

After researching the seemingly endless list of rain jackets on the market, we took the most promising out for testing to narrow our final list to what we found to be the best rain jackets for running. The team at iRunFar tested these running rain jackets in some seriously wet — and snowy — conditions, from desert downpours to drizzle in the Pacific Northwest to summertime storms in Colorado’s San Juan mountains to atmospheric river events in California, to determine the best options for rainy adventures. Our team consists of professional and recreational ultra and trail runners who aren’t afraid to get out when others stay inside. We took these jackets through the worst weather conditions to see which ones kept us dry and which ones left us soaked and sprinting for home, shivering. Below are our top picks

  • Excellent waterproofing
  • Lightweight and comfortable
  • Excellent fit


  • It is a little tough to fit in the built-in stuff pocket

We already liked Patagonia’s Storm Racer Jacket quite a bit. It checked a lot of boxes we look for in a solid running rain shell. Lightweight? Check. Solid rain protection? Yes. Durable material? You bet. Breathable? As much as can be expected for a fully waterproof shell. Our one qualm? We didn’t love the pullover style with the side zips. Now we get everything we loved about the original version but with a traditional front zipper that we like a bit more than the previous design.

First, we noticed the fit continues to be a slim, athletic cut, which we also love. While some brands have boxier cuts that offer more room for generous layering underneath, we prefer the cut that fits closer to the body. We also appreciate how well this jacket blocked out the rain during many runs through some atmospheric river events in California. We took it to higher elevations, where it held up well in some wet snowfall in the San Bernardino Mountains. Could this jacket be more breathable? Of course. Pretty much any solid rainshell does. But we’ll take the tradeoff for confidence in a fully waterproof, lightweight, and comfy shell.

Beyond its performance, we have to commend Patagonia for being one of the leaders in a more planet-friendly way of constructing rain gear. Patagonia employs a 100% recycled nylon ripstop fabric with a durable water-repellent (DWR) coating free of perfluorinated chemicals (PFCs/PFAS). We’re here for it.

Claimed Weight (men’s): 204 grams (7.2 ounces) | Material: 2.2-oz 20-denier 100% recycled nylon ripstop face with a 7-denier tricot backer, a waterproof/breathable barrier and a durable water repellent (DWR) finish made without perfluorinated chemicals (PFCs/PFAS) | Construction: Three-layer construction

Best Running Rain Jacket – Runner-Up: Montbell Rain Trekker Jacket ($230)

Best Running Rain Jacket - Montbell Rain Trekker Jacket - product photo


  • Quiet fabric
  • Waterproof yet reasonably breathable
  • Fewer seams for potential moisture entry


  • Separate stuff sack could be easy to misplace
  • Not as breathable as some other jackets tested

The Montbell Rain Trekker Jacket is a feature-filled jacket that earned high marks from our testers for its waterproofness and breathability. Montbell built this jacket using a single piece of fabric. This unique K-Mono Cut design reduces both weight and the number of seams for better protection from the elements. The fully sealed seams prevent moisture from seeping in.

The Gore-Tex Infinium Windstopper waterproof membrane is paired with a 20-denier nylon outer with a durable water-repellent (DWR) coating to create a lightweight yet protective two-layer jacket that our testers found functions well on both rainy days and in winter snowstorms. Multiple adjustment points on the hood, cuffs, and hem allow for a customizable fit to optimize comfort and better protect from wet weather.

Additional features include a water-resistant zipper, hook-and-loop closures to secure the hood when not in use, and a sewing pattern that allows for arm range of motion without pulling on the body of the jacket. We found this fabric to be quiet while moving, a bonus for those who get annoyed by the incessant crinkling and swishing sounds that many rain jackets make during a run.

We found the sizing adequate for layering and wearing a small pack underneath, but you will likely need to size up for bulkier layers or a larger loaded pack. Two waterproof external pockets on the chest can accommodate small items for easy access. The jacket also has a separate stuff sack for storing it on the go.

Best of the Rest Running Rain Jacket: Outdoor Research Helium Rain Jacket ($170)

Best Running Rain Jackets - Outdoor Research Helium Rain Jacket - product photo


  • Lightweight and easily packable
  • Nice features for the price make it a good value
  • The hood is the best we tested


  • It can feel muggy in warmer temperatures due to less breathability
  • Zipper can be fragile
  • Will soak through in heavy and continuous rain

The Outdoor Research Helium Rain Jacket is a lightweight, waterproof jacket that packs a lot of punch for its price point. While it certainly isn’t inexpensive, the number of features and protection it offers make it well worth the investment. This is a 2.5-layer jacket featuring a Pertex Shield waterproof membrane coupled with a 30-denier nylon outer to provide water protection in a very lightweight package. It has fully taped seams, a water-resistant zipper, and an adjustable hem and hood. The zipper is tiny — zip with care to not damage it. We loved the hood of this jacket and found that it easily fit a winter or brimmed hat underneath it. It also provides plenty of room for a ponytail. An adjustable bungee kept it in place when the rain and wind hit.

The single zip pocket on this jacket also serves as a stuff sack for storing the jacket when not in use. The somewhat relaxed fit allows for some layering, but it’s not so loose that it flaps around while on the move. We recommend sizing up to accommodate thicker layers or a hydration pack underneath. The jacket is less breathable than others we tested and felt a little muggy on warmer runs. Our long-term testers found that the jacket became less waterproof with extended use and would start letting water through during longer stints in heavy rain. But for its weight and price, it performs exceptionally.

  • Pit zips provide ventilation and heat management
  • Lightweight with excellent waterproofness
  • Reduced number of seams


  • Lighter-weight nylon outer may prove less durable
  • Outer material is louder than others tested

The Montbell Versalite Jacket is another excellent offering from the Japanese company. This jacket shares many features with the overall winner we reviewed above, the Montbell Rain Trekker Jacket. These include the fully sealed seams, adjustable hood, hem, and cuffs, articulated arm design, water-resistant zippers, pocket configuration, stuff sack, and the seam-reducing K-Mono Cut design.

While there are many similarities between the two jackets, several features make this one significantly different. The jacket uses the same Gore-Tex Infinium Windstopper waterproof membrane but with a lighter 10-denier durable water repellent (DWR)-coated nylon outer. This reduces the weight, but we did notice that the outer material was a little louder and crinklier. The 10-denier nylon does raise a question about long-term durability, but our testers have not yet encountered any issues after months of testing.

The large pit zips make this jacket stand out from others that we tested and are a feature that seems to be rare amongst running jackets. The zips offer a lot of venting for dumping excess heat, making it easier to control body temperature while wearing the jacket. This jacket is an excellent option for runners needing full waterproof coverage in warmer climates or running a bit hot.

Best Ultralight Running Rain Jacket: Rab Phantom Waterproof Pull-On Jacket ($215)

Best Running Rain Jacket - Rab Phantom Waterproof Pull-On Jacket - product photo


  • Very lightweight and packable
  • Material has some stretch for comfort and ease of movement
  • Stuff sack included for packing


  • Slim fit is more challenging to get on and off and does not accommodate many layers or a pack underneath
  • Material is noisy when moving

The Rab Phantom Waterproof Pull-On Jacket is an anorak-style waterproof jacket that topped our list for its impressively light weight and breathability. The jacket features a 2.5-layer construction with a Pertex Shield waterproof membrane and fully taped seams for maximum protection. To save weight, this ultralight jacket skips bungees on the hood, cuffs, and hem and lacks adjustability. It also doesn’t have any pockets. The water-resistant zipper was smooth and moved well with no catching. The material has some stretch, making it comfortable on the move, but it is louder than some of the other jackets on the list, which can be distracting on the trail. It has a slimmer profile and tighter fit, which is useful for keeping the jacket from shifting or flapping while on the move or in the wind, but it does make it more challenging to take on and off quickly while running. You’ll want to size up if you want to wear heavier layers or a pack underneath it. Additionally, we found the material of this jacket to be much louder than some of its counterparts, which can be distracting out on the trail.

Best Ultralight Running Rain Jacket Runner-Up: Montane Unisex Minimus Nano Pull-On Waterproof Jacket ($170)

Best Running Rain Jackets - Montane Unisex Minimus Nano Pull-On Waterproof Jacket - product photoPros:

  • Lightweight
  • Highly waterproof
  • Decently breathable
  • Packs down very small


  • Not everyone will love the slim fit and pullover style

If weight is of the essence when choosing a rain jacket, it’s hard to go wrong with the Montane Unisex Minimus Nano Pull-On Waterproof Jacket. Weighing just 3.9 ounces (100 grams), it really is a jacket that you can always have in your pack in case the weather takes a turn for the worse — we regularly swap it from running vests to day packs to fly fishing hip packs. It comes with its own stuff sack, making it easy to keep in your pack whenever you head out. But a rain jacket needs to be more than just light; it has to keep you dry as well, and this jacket does just that. Made of Montane’s waterproof and breathable Aqua Pro Light fabric, it’ll keep you protected from wind and rain while minimizing any sweat buildup. It’s been one of our go-to shells for multiple years.

While not adjustable, the hood has elastic in the back to help it stay on your head. It also has a bit of a peak to help shed water off the sides and keep it from dripping into your face. When the jacket is fully zipped up with the hood up, it provides a lot of coverage around the head and face. The hem and the cuffs are both elastic, an easy way for the jacket to save weight without compromising functionality or comfort. Our one nitpick — like many other rain shells — is it could be more breathable.

The half-length zipper is enough for shedding heat when needed, and it helps save weight by not being full-length.

Running Rain Jackets Glossary

The technology that goes into high-quality waterproof outdoor gear, such as running rain jackets, is impressive — and can get confusing! We share some definitions for common waterproof gear terms to help clarify their meanings.

  • Durable Water Repellent (DWR) Coating: A coating applied to fabric that causes water to bead up on the surface and roll off, keeping it from soaking into the material. Due to environmental concerns, DWR coatings are historically fluoropolymer-based, though many companies are working toward using non-perfluorinated chemicals (non-PFC).
  • Moisture Vapor Transmission Rate (MVTR): A laboratory testing method to measure a material’s breathability by the amount of moisture vapor (our sweat) that can pass through the fabric. It is measured in grams of vapor per square meter of fabric per 24 hours. The higher the number, the more breathable the material. A moderate breathability rating starts at around 10,000 g/m2.
  • Resistance to Evaporative Heat Loss (RET): Another measure of the breathability of material that measures the material’s resistance to water vapor. The lower the resistance, the more vapor can pass through. The lower the RET, the more breathable the material, and a rating of less than 13 is considered good breathability during activity.
  • Hydrostatic Head Test: A laboratory test to quantify the waterproofness of a material. Material is stretched over the end of a one-inch diameter tube, and a column of water, measured in millimeters, is added to the tube and observed for 24 hours. The rating measures how many millimeters of water a fabric can hold before it soaks through and is measured in millimeters of water pressure. The water height at which the water seeps through the fabric is called the hydrostatic head. The higher the number, the more waterproof the material, with the lower end of waterproof jackets starting at around 10,000 millimeters.
  • Schmerber Unit: Another name for the hydrostatic head waterproofness measure named for Charles Edouard Schmerber, who created the hydrostatic head test.
  • Waterproof Membrane: A synthetic material membrane that blocks and repels water. It is usually bonded or layered with an outer material layer and/or inner liner to create a waterproof jacket. Common brands include Gore-Tex, eVent, Polartec Neoshell, and Pertex.
  • Denier: Measurement of the thickness of a material’s fiber. A higher denier denotes a thicker and often more durable fiber.
  • Wetting Out: The point at which the amount or pressure of water overwhelms the waterproof capability of a jacket material.

Buyer’s Guide: How to Choose a Running Rain Jacket


Just like any other piece of clothing, fit is the most important aspect of a jacket and is subjective from person to person. Do you want something that fits a bit tighter or a jacket that you can wear with layers underneath? The fit and coverage of rain jackets should prevent moisture from getting in, even if you are bending over or moving your head around.

Accommodating a pack is another consideration when choosing your jacket. Some runners prefer to wear a jacket under their pack, while others would rather wear it over their pack to keep gear dry and make it quicker and easier to take on and off. Some jackets intentionally fit a pack underneath, but most will require sizing up to do this.

The best rain jacket for running will cover your wrists well and the hem will stay below your waistline when you raise your arms. Some jackets, such as the Montbell Rain Trekker Jacket, have elastic cords that allow for some cinching of the hem, cuffs, and hood to keep them securely in place and help provide a more custom fit. A jacket should also have enough room in the shoulders or adequate stretch in the material to allow for full range of arm motion when running, including reaching for things in your pack, scrambling on technical trails, or just bending over to tie your shoe.

An important thing to remember when considering fit for a rain jacket is that some waterproof options, like the Outdoor Research Helium Rain Jacket, don’t have much stretch or give to the materials, so this is an item of clothing you may want to size up on to allow for freedom of movement and layering.

Waterproof Versus Water-Resistant

The waterproof protection offered by running jackets varies from repelling a few sprinkles to keeping out a monsoon. A water-resistant jacket will protect from a brief shower with the help of a durable water-repellent (DWR) coating. While water-resistant jackets are lightweight and packable, they will not keep you dry in extended wet weather, as the underlying materials are not waterproof themselves, and persistent rain will overwhelm the DWR. You can check out our running windbreaker jacket guide for some great examples of lightweight, water-resistant running jackets.

Waterproof jackets can repel water from their surface and prevent water from seeping into and soaking through the fabric. These will keep you dry during prolonged wet conditions, such as a long, soaking rain or wet snowfall.

Waterproof jackets are often composed of multiple layers of materials that repel and shed moisture and often include a DWR coating. Vulnerable areas, such as openings around the neck, hood, wrists, and zippers and seams, tend to feature additional protection. A fully waterproof jacket is the gear you will need for true protection from the elements. All of the features of Patagonia’s Storm Racer Jacket, including its waterproof qualities, led us to name it the best running rain jacket.


The primary purpose of a rain jacket is to keep you dry. However, the tradeoff for this is often breathability. The best running rain jackets have come a long way from plastic bag-like ponchos, and many offer excellent moisture protection and breathability. The conditions in which you will be using your jacket can inform the balance of these two features you choose. For brief showers in warm climates, you can sacrifice a little waterproof capability for more breathability, whereas you may want to prioritize waterproofness in an all-day soaker with temperatures hovering just above freezing. The Montbell Versalite Jacket has pit zips to increase its breathability without sacrificing the waterproofness of the jacket material and is an excellent option for running in changing or warmer but wet conditions.

Waterproof jackets improve their breathability by using fabric with permeable membranes that have microscopic holes big enough to let water vapor from your body escape but small enough to block water droplets from the outside. This technology comes at a premium, though. Generally, the more lightweight and breathable a waterproof jacket is, the higher the price tag. A pricey jacket with all the bells and whistles may not make sense for everyone, but if you are spending hours running in a cold and soaking rain, the combination of good breathability and waterproof capability can quite literally be a lifesaver.

Some laboratory values quantify a jacket’s breathability — see our answer to the frequently asked question “How is breathability measured?” below. These measures give a reference point for the objective breathability of a material, but as with many types of technology that are analyzed in a lab, real-world performance doesn’t always agree. Real-world breathability can depend on several external factors, like temperature, humidity, or a person’s sweat rate.


Staying dry when the wet weather rolls in is why you are looking for the best running rain jacket. As we mentioned above, how a rain jacket provides waterproof protection will vary from brand to brand, but generally, it is a waterproof membrane — such as Gore-Tex, eVent, or Pertex — that layers with other fabrics.

A rain jacket often features either two, 2.5, or three layers. In a two-layer jacket, such as the Montbell Rain Trekker Jacket and Montbell Versalite Jacket, an outer layer of durable water repellent (DWR)-coated nylon is layered or bonded to a waterproof membrane, such as Gore-Tex or similar.

A 2.5-layer jacket, such as our ultralight winner, the Rab Phantom Waterproof Pull-On Jacket, adds a coating on the innermost layer of the jacket to protect it from body oils, sweat, and other substances that can degrade the material. This coating is a half layer because it’s not a complete material layer.

A three-layer jacket features the outer layer bonded to the waterproof membrane, with an additional full inner layer of material. A three-layer jacket will, in theory, give you the most protection from the elements but at an increased weight and with reduced breathability.

When choosing a running jacket, more is not always more when it comes to layers. Most of our top choices for this guide are two- or 2.5-layer jackets, and that’s because we have found them to have the balance of waterproofness and breathability that runners want.

In addition to the materials and layer structure of the jacket, additional features such as taped seams and water-resistant zippers add an extra layer of protection to keep you dry.

There are several features to look for that enhance the fit and function of a quality waterproof jacket. While there are a whole host of bells and whistles that companies may tout to set their jackets apart from the rest, there are a few key features that we think are the most important to consider when shopping for an excellent running rain jacket.

  • Hood: First, a well-fitting hood is necessary to keep rain and snow out. At the very least, the hood should include some elastic edging, like our top ultralight jacket, the Rab Phantom Waterproof Pull-On Jacket, to allow it to stretch around your head and face and stay in place while moving. A more full-featured jacket, such as the Montbell Rain Trekker Jacket, will have additional adjustment points, usually in the form of elastic draw cords, on the front and back of a hood that will help to cinch it in place, adjust the brim, and allow the hood to follow your head movements. A built-in brim on a hood, like the one on the Outdoor Research Helium Rain Jacket, will help to shed water and protect your face from the rain.
  • Taped Seams: Seams are an unavoidable weakness in any jacket’s waterproofness that can allow moisture to get in. Fully waterproof jackets remedy this problem with a layer of material, usually thermoplastic tape, that is bonded and heat-sealed over the seams on the jacket’s interior.
  • Zipper: Another potential moisture entry point on a jacket is the zipper. All the jackets featured in this buyer’s guide use water-resistant zippers that help seal out the elements. The technology in these zippers can cause some to move slower than a traditional fabric zipper, and some of the smaller zippers are delicate.
  • Adjustment Points: In addition to the elastic adjustments on the hood discussed above, many jackets will also include an elastic cord on the hem or waist to allow the wearer to cinch the bottom of the jacket and dial in a secure fit. Cuffs are another adjustment point, with some jackets including an elastic cinch, thumb loop, or Velcro strap to tighten or secure the cuffs to keep the sleeves from slipping or riding up with arm motion.
  • Pockets: Several of our top pick jackets have at least one pocket that can stash smaller items for easy access on the move. Using the jacket for extended periods versus a just-in-case packable layer for short rains will help guide your desire for an outer pocket. Bear in mind that pockets add zippers, create more seams, and add extra weight. You’ll want to forego pockets if you are looking for a lightweight jacket. Included pockets often serve as a built-in stuff sack for packing the jacket away.

As material technology advances, so does the ability to have ultralight clothing. Men’s jackets, just by the nature of sizing and body mechanics, will be slightly heavier than women’s, but we can now measure that difference in grams rather than ounces. The more durable the material and the more bells and whistles, like pockets, zippers, and hoods, the heavier the jacket will be.

Our heaviest pick was the Montbell Rain Trekker Jacket, weighing around 200 grams. For a real-life reference, this is about the weight of a cup of sugar. The ultralight Rab Phantom Waterproof Pull-On Jacket came in at around half that, but that lightweight package means you are giving up some convenience factors like adjustable bungees on the hood and hem.


We trail runners aren’t always known for traveling light. We sometimes have something to stash, like our keys, snacks, or headlamp, and we like our pockets! But as we’ve said, there’s a tradeoff: more storage results in a heavier jacket. If you’re on an adventure where you want a jacket with many pockets, you’re likely wearing something else with pockets, too, like a running pack, running shorts, or running belt.

Your rain jacket may be the one item where sacrificing storage and pockets is a wise choice. Storing items in a jacket will also up the bounce factor considerably and can create some issues with the fit, potentially creating gaps for water seepage. The Rab Phantom Waterproof Pull-On Jacket skips having pockets completely to alleviate the extra weight and potential problems caused by adding them.

Often, a rain jacket is more of a just-in-case layer during a long event or is put on during a rain shower and taken off once things dry out. It is also part of the mandatory kit for several events. Your rain jacket will frequently just be taking a ride in your pack or waistbelt during a run, so it needs to be — you guessed it — packable.

Packability goes hand in hand with weight — usually, the lighter the jacket, the smaller it will pack down. Many of our top jacket picks have an internal pocket that the body of the jacket can roll into, producing a package no bigger than your fist that you can easily stuff into a hydration pack. Others are a bit bulkier but provide increased insulation, waterproofing, and storage capacity. Those looking to shave as much weight and volume possible with a jacket will gravitate towards a lighter jacket, like the Rab Phantom Waterproof Pull-On Jacket, the lightest jacket we tested. But, if you know the conditions will be wet, you might want to take the weight penalty and take a more robust jacket, such as our top pick, Patagonia’s Storm Racer Jacket.

You’ll likely have to layer your jacket over lighter layers, a hydration pack, or another jacket. In many situations, it often makes sense to size up to give you room to fit your jacket over cool weather layers. A little more breathing room also means putting your jacket on right over your pack, keeping your other gear dry, and making donning and doffing your outer layer quicker and easier. Slimmer-fitting jackets, like the Rab Phantom Waterproof Pull-On Jacket, must be sized up to add heavier layers underneath.

Why You Should Trust Us

Many members of the iRunFar team are based in the mountains, such as the San Juans of Colorado, or play in the high peaks of the U.S. Pacific Northwest, where some of the most unpredictable weather can occur. We’re used to sunny days turning to rain or a soft snowfall suddenly turning to a screaming sleet storm. We understand the importance of having a waterproof rain jacket that we can trust to perform when the weather worsens. We are committed to testing the best products out there in a variety of conditions so that you don’t have to suffer through the same trial and error out in the elements.

We started our testing process with market research: who is making the best product? We then polled our readers and iRunFar team members to choose more than 20 rain jackets to test. What you see in this guide is the result of over one year of testing for all those jackets, where we ran them through winter snowstorms, cold dousers in the U.S. Pacific Northwest and high-altitude mountain west, humid rainstorms, desert soakers where wet sand coats all surfaces, and everything in between to find the best running rain jacket for any type of weather condition.

Frequently Asked Questions About Running Rain Jackets

Do I need a fully waterproof rain jacket for running, or will water resistance be good enough?

This will largely depend on the climate in which you typically run. A warm-weather runner who might encounter an occasional shower can certainly get by with a lightweight, water-resistant jacket for those just-in-case moments.

For trail runners heading into the mountains or out for hours in constant rain and chilly temperatures, we recommend a fully waterproof jacket like the Montbell Rain Trekker Jacket for comfort and safety. The combination of cold air temperatures and wet skin creates a high-risk scenario for hypothermia, which can quickly become life-threatening. Having the proper layers to protect against these elements means you will comfortably enjoy your adventure — and make it home to talk about it.

In addition, many races, particularly those in mountainous terrain or in cold, wet climates, have mandatory kit lists that require participants to carry a waterproof jacket for the duration of the event.

How are waterproof ratings measured on rain jackets?

While its performance in real-life conditions best determines the waterproofness of a jacket, laboratory testing helps establish a baseline rating for the materials used in the construction of waterproof clothing.

The most used measurement is the hydrostatic head, which measures the amount of water a material can withstand before it starts to saturate and leak through. In this test, the fabric is secured over a one-inch diameter tube underneath a column of water of a certain height, and the material is observed for 24 hours.

The height of the water column at which the water starts to saturate through the fabric and leak is the hydrostatic head, measured in millimeters. A hydrostatic head measurement of 10,000 millimeters is considered the baseline for waterproof jackets.

Please note that while many manufacturers will list hydrostatic head numbers in the specifications for their jackets, not all materials use this rating. Gore-Tex, which the Montbell Versalite Jacket and the Montbell Rain Trekker Jacket use, employs its own rain room to test its garments using specially designed rain nozzles and wind simulators to better approximate actual weather conditions.

How is breathability measured in a rain jacket?

Two types of laboratory-bestowed ratings quantify breathability. The first and most seen is Moisture Vapor Transmission Rate (MVTR). MVTR measures the rate at which moisture (your sweat) permeates through the fabric. The higher the MVTR rating, the better, with good values starting around 10,000.

The second is Resistance to Evaporative Heat Loss (RET), which measures the material’s resistance to water vapor. The lower the RET, the better the breathability.

In theory, these numbers correlate to the breathability of the jacket. In practice, many other factors impact a jacket’s comfort and breathability, and we prefer comparing performance in real-life conditions to making a purchase based on a lab value. Patagonia’s Storm Racer Jacket’s relatively good breathability was one factor that led us to name it our best rain jacket for running.

How long will a rain jacket’s waterproofing last?

Sadly, nothing lasts forever, but with proper care and maintenance, you should enjoy many dry and comfortable years with your waterproof jacket. Several factors will impact your waterproof jacket’s lifespan. Repeated exposure to rain and sweat or body oils will start to wear away at the material’s waterproof coating and membrane over time. Jackets with 2.5-layer construction, like the Rab Phantom Waterproof Pull-On Jacket, have an inner layer to protect the rest of the jacket from sweat and body oils.

To prevent material degradation, all jackets will come with specific care recommendations, most often avoiding standard detergents and high heat exposure, such as a clothes dryer. That doesn’t mean you should never wash your jacket. Occasional washing with a laundry soap specifically formulated for waterproof materials will remove dirt and body oils that wear out waterproof fabrics and extend the life of your jacket.

An easy way to extend the life of a waterproof jacket is by refreshing the durable water-repellent (DWR) coating. Apply a few drops of water to the exterior of your DWR-coated jacket — if the water soaks in instead of beading up and rolling off, your jacket has lost its water-resistant outer coating.

You can reapply a DWR coating using a spray-on or wash-in product, such as Nikwax, that will bond to the outer material and refresh the jacket’s water-shedding capabilities. Always check your jacket’s care instructions and the instructions on the DWR-replenishment product before applying to be sure it is safe to use on those materials.

Is there a big difference between men’s and women’s rain jackets for running?

Along with other clothing items, jackets feature designs for men’s and women’s specific body shapes. Wide versus narrow shoulders, a straight cut versus a waist taper, and wider and narrower hips are only a few differences between jackets made for different body types. Of course, if you find a jacket traditionally made for a different body type that feels the best for you, go with that one! The Rab Phantom Waterproof Pull-On Jacket is slimmer than many other jackets we tested, while the Outdoor Research Helium Rain Jacket has a much looser overall fit.

Most brands make equivalent models in both men’s and women’s jackets.

Do I need to size up when buying a rain jacket?

While the overall sizing of different rain jackets is fairly standard, they all have various cuts and fit an array of body types differently. If you generally only toss a rain jacket on over a single layer, or maybe a thin insulating layer, you can probably get away with the same sized rain jacket as the rest of your running wardrobe. But it’s probably worth sizing up if you’re running in environments where you have to layer up underneath a rain jacket. If you want to be able to wear a small pack under your rain jacket, sizing up is a good idea, too. While the material in many rain jackets has some stretch to it, a jacket like the Outdoor Research Helium Rain Jacket doesn’t have a lot of give to it and can inhibit range of motion if it’s too small. Choosing the larger size is often worth it if you’re between sizes.

Should I prioritize weight or protection in a rain jacket?

This comes down to personal preference and how much you can spend. Generally, the highest-priced items will offer both minimal weight and maximal protection. But if your budget is minimal, you’ll likely have to sacrifice a bit of one or the other. If weight is your biggest concern, the Rab Phantom Waterproof Pull-On Jacket is a great option. In the end, the best running rain jacket is one you’re willing to carry, even if it’s not the most protective one available, so you’ll want to get one you’re not averse to putting in your pack for any run.

Is it worth paying more for an expensive rain jacket?

While technically, you can run in a trash bag or an inexpensive $3 poncho and stay relatively dry, investing in a high-quality rain jacket is a good idea in the long run (pun intended). A good rain jacket can protect you from the rain while allowing moisture from sweat to escape from the inside. A breathable and waterproof jacket isn’t inexpensive, but it can make running in the rain much more comfortable and safer. Well-constructed rain jackets can also last long and be considered a significant investment in your running gear. Proper care of a 2.5-layer jacket like the Outdoor Research Helium Rain Jacket can keep it waterproof for a long time, as can adding a new DWR coating when it loses its waterproofness.

Eszter Horanyi identifies as a Runner Under Duress, in that she’ll run if it gets her deep into the mountains or canyons faster than walking would, but she’ll most likely complain about it. A retired long-distance bike racer, she gave ultra foot racing a go and finished the Ouray 100 in 2017, but ultimately decided that she prefers a slower pace of life of taking photos during long days in the mountains and smelling the flowers while being outside for as many hours of the day as possible. Eszter will take any opportunity to go adventuring in the mountains or desert by foot, bike, or boat, and has lived the digital nomad lifestyle throughout the west for the past seven years.
