GU Soft Flask


GU teamed up with their 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 5 servings of Energy Gel and includes marks on the back to measure your fuel.

Fill it with Energy Gel from their new 15-Serving pouches, fuel with it, and reuse it!
