Light and Comfortable

  • Familiarity: I've put it through the wringer

I used this for a 100k race in Idaho recently. The vest is light and very comfortable. I had no chafing. The bladder is very easy to fill without removal making aid station stops quick. There is enough room for a rain jacket and the tailwind I needed but barely. For me, the pack would be a bit too small for a 100 miler if running without a crew. Other than that it is great. I have several Ultraspire packs and like most of them. This is one of the best. The 2.0 version has elastic cords across the chest that permit chest expansion...a great feature.
