GU Energy Flask

Gu teamed up with their 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!
