The Scott Jurek Ultra Vest has been replaced with the Ultimate Direction Scott Jurek Ultra Vest 2.0! We still have a few of the original packs (slightly lighter) available for sale.
The Ultimate Direction Signature Series SJ Ultra Vest is the result of collaboration with Scott Jurek, the world’s most dominant ultra runner. Weighing in at 7.5 ounces (13 with bottles) and offering 9.2 L of storage space, the SJ has the best weight-to-capacity ratio of any hydration pack on the market.
I’ve been using Ultimate Direction packs for years, modifying them to carry bottles in front…the Ultra Vest is the culmination.
- Weight: 7.5 oz (213 g) / 13.0 oz (369 g) with bottles
- Capacity: 9.2 liters total volume
- Bottles: 2 x 20 ounce
