GU Energy Gel Flask

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 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 of Salted Caramel or Strawberry Banana gel, fuel with it, and reuse it!
