I like this item so much that I want to buy all of them so no one else can have them. Just kidding, kind of. I recently ran a marathon with them, and was able to pack all my nutrition in the forearm pockets, and water in the shoulder pockets using some small water bottles I bought from the store. I had been running with a handheld bottle during my training, so my arms were already used to the weight. Having my hands completely free was an excellent feeling. They also turned a cooler morning into a pleasure on my arms. Before the race began, I had about five other people ask my where I got them from. Do yourself a favor, and buy this product which will make your life much better during your longer runs. An excellently engineered and executed idea!!! Were talking Shark Tank time.
