Perfect for a long day on the trails.

  • Familiarity: I've used it several times

Between the additional 1.5L bladder you can buy to the two 12 oz. bottles you can hold on the shoulder straps this hydration vest is the best of both worlds. From a short trail run to training for your first 50K this vest is there to go the distance.

There is enough room in the back to carry some gloves, an outer layer, some bars, whatever you need to stay fresh and ready for the trails. The expandable pouch is perfect for a few gels or blocks and the mesh allows it to stay close to your body and not bounce around.
