GU Energy Refillable Flask for Sports Nutrition Energy Gel, 5.5-Ounce

We teamed up with our neighbors at hydrapak to design a customized soft-flask with a high-flow nozzle to make fueling for long efforts more convenient and less sticky. The Flask holds 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.
