GU Energy Gel Flask BPW Quieter than everWe teamed up with our neighbours at Hydrapak to design a customised soft flask with a high flow nozzle to make fueling for long efforts more convenient and less sticky. The Flask holds 5 Servings of Energy Gel and includes marks on the back to measure your fuel. Fill it with Energy Gel from our new 15 Serving pouches, fuel with it, and reuse it!
