      Fits great . Does the job

      Fits great and it does the job. Good quality vest.

      well worth the wait

      I wanted a good quality hydration vest that fit me properly. The Spartan Weis vest hugs my upper body and I dont even know it is on. A great number of pockets to carry gels, waffles and chewing gum. i also like the small side pocket with a hook for my car keys, something you dont want to loose when running down a trail and opening up pockets. This vest was out of stock for a while, but i was really happy to find it back in stock, so I jumped on it. Really works well for me and I highly recommend it

      Definitely does the job

      As far as hydration vest go this is by far my favorite, I just wish it came in more color options


      I love my vest it holds everything I need and I can even fit a finisher shirt in the back so they don’t run out before I finish the races. I can also hold an extra bottle of water in the back. Perfect amount of pockets. In the front and sides .
