Black Diamond is a company long known for their highly technical climbing and alpine gear. Over the last several years, they have expanded their scope to include trail running and fastpacking gear that takes the same technology as their mountaineering apparel and pares it down for fast-moving backcountry trips.
A lot of what I personally look for when I’m packing for a mountain ultramarathon happens to land in four categories: an all-day t-shirt, a lightweight wind/rain jacket, an ‘oh shit’ rain jacket for really severe weather, and a lightweight insulated jacket. I’ve mixed and matched over the years with apparel from various brands. Most of my favorites have holes and duct tape holding them together and they’ve often required a lot of layering to really stay warm overnight in an ultra when the weather turns. Over the past six months, I’ve had the pleasure of putting several jackets and a t-shirt from Black Diamond through their paces and have come to appreciate how protective, durable, and comfortable they are.
Black Diamond Rhythm Tee
The all-day t-shirt… or maybe, the all-week t-shirt. It’s a balance of trying to find the wicking abilities of a synthetic material without having to deal with the dried salt and grime that makes most polyester shirts become inflexible and chafe. Or, maybe you’ve been looking for a running shirt that isn’t made from crude oil? Either way, the Black Diamond Rhythm Tee ($75) is my first choice for an all-day or overnight outing.
Imagine a shirt with the warmth of Merino wool when wet with the drying capabilities of the lightest polyester running shirts and you’ve got the Rhythm Tee. When I say lightweight, I mean incredibly lightweight. At 2.4 ounces (69 grams), this shirt is 1.5 ounces lighter than The North Face’s Better Than Naked Short Sleeve t-shirt. The Rhythm Tee almost disappears on your body. Additionally, this shirt has some stretch which makes it move better with your body and it’s so much lighter than other Merino shirts on the market. Black Diamond uses NuYarn fabric which is made of a super-fine nylon core wrapped in Merino to create a shirt that is reportedly 35% stretchier, five times faster drying, 25% warmer, and 16% stronger than standard Merino wool. Another huge bonus is that this shirt is machine washable.
I’ve worn the Rhythm Tee more than any other shirt I own this summer and fall, from 90-degree-Fahrenheit runs where I felt like I was melting to cold mornings at 40 degrees Fahrenheit. I even wore it for every run in one week without washing it, and the shirt barely smelled by day seven. Even better, it doesn’t seem to lose its stretch or absorb the salt from my sweat and get abrasive. I haven’t found durability issues, but I have talked to runners whose Rhythm Tees sported small holes from snagging. This will be the shirt I’ll start my next 100 miler in and I doubt that I’ll change out of it.
Black Diamond Alpine Start Hoody
There are a lot of featherweight wind shirts/jackets out there that work okay until the level of precipitation or temperatures start to get real. Then you find those sub-four-ounce shells sticking to your arms and torso after the thin membrane has been breached and it actually makes you feel colder. If rain is expected, some of these jackets can be next to useless.
The Black Diamond Alpine Start Hoody ($165) is a bit more robust (7.4 ounces/210 grams) and with good reason. Originally designed as a minimalist climbing jacket, the Alpine Start Hoody has a bit roomier feel than most lightweight running jackets and it seems to work with your range of motion better. While fairly protective from heavy rain and snow, I am also impressed with how breathable it is. I often find myself constantly taking off or putting on jackets as the weather and my pace change. With the Alpine Start Hoody, I never feel clammy underneath and I consistently leave it on for entire runs only adjusting the snugness of the zipper. This jacket is easily packable into its breast pocket and features a usable hood that stays put thanks to a zipper design that sits right beneath your chin and doesn’t chafe or bounce.
I’ve found the Alpine Start Hoody to be incredibly versatile, and it has been my most used jacket over the last six months. I can layer underneath it for runs as cold as 30 degrees Fahrenheit or when I’m doing a high-intensity workout, and I can easily take it with me for cold morning starts where things will warm up. I’ve also taken several diggers while running in this jacket and it remains hole free.
Black Diamond First Light Stretch Hoody
I love me a good puffy, and I’ve been known to finish a long ultra in a puffy coat and then immediately put on even more puffies afterward to stave off the shivers. The problem with this is two-fold. First, I often overheat, and less importantly, I look ridiculous. The Black Diamond First Light Stretch Hoody ($259) provides the warmth that I’m looking for from a thin puffy jacket with the breathability and function of a lighter weight running jacket. The outer layer is made of Shoeller stretch woven nylon with a DWR coating over a layer of Primaloft insulation. The hoody also has liner made of stretch woven polyester. It can handle some rain and wet snow without soaking through all while maintaining loftiness and breathability.
Again, designed as a climbing jacket, I love the feel of unrestricted movement from the First Light Stretch Hoody. The cut of the jacket is svelte and I never feel like a running marshmallow which is how I feel with most insulated jackets. It’s been a great jacket for under 20-degree days to chilly mornings when motivation is low and the dogs are staring at me longingly. For a typical 30- to 40-degree morning, I can throw it on over a t-shirt and get out the door quickly before I start to question my motivation.
Black Diamond Liquid Point Shell
I’ve mentioned the need for an ‘oh shit’ jacket in past apparel reviews, and the Black Diamond Liquid Point Shell ($259) is the quintessential version. Weighing in at 14 ounces (395 grams), it may seem like a bit much for an ultra, but if you’ve ever DNFed due to hypothermia in the rain or snow you may not think so. The Liquid Point Shell does not feel heavy when it’s on, and again, the freedom of movement due to underarm gussets makes it fit more comfortably and breathe better than other GORE-TEX jackets I’ve worn. Think of it as a minimal GORE-TEX shell with all of the weather protection you need but none of the bulk.
In a downpour with the zipper up, Black Diamond placed a nice piece of soft fabric over the inside to cozy up to, and the adjustable hood creates a fully protective membrane which keeps rain from getting inside. Two zippered hand pockets on the front make the jacket a lot more versatile and allow you to store nutrition, keys, or a phone with easy access. Due to the breathability of this jacket and some major underarm vents, runners in very wet areas may appreciate this as a winter jacket to layer under.
Black Diamond Apparel Overall Impressions
It’s usually interesting when companies who primarily focus on other sports make forays into the trail and ultrarunning world. Sometimes these designs are excellent, but at other times they just feel like a pared-down version of the company’s best offerings. Black Diamond may not market most of these jackets as trail running specific, but they work incredibly well and offer more comfort due to the dynamic movement needs of climbing. These jackets perform and breathe as well as any I’ve tested, and their durability means that your purchase will last for many years. On an insignificant side note, they also simply look better than most running-specific jackets, and if you’re investing in a piece of gear like this it is nice to be able to run errands or walk into work without looking like you’re in running gear or on an expedition.
