We came up with the idea for the Wedge during a training run when all I needed was an 8oz FuelBelt bottle and a gel packet. I tucked the bottle between the elastic band of my run shorts and my lower back/butt. It was an instant hit but needed some added security, so we added a small clip to keep the bottle from slipping downward. It provides you with the ultimate hands-free/waist-free experience, but still allows you to carry several ounces of fluids with you for that quick run. The smooth contoured bottle is very comfortable tucked behind your waist or at the side of your hip.
