Why We Love It
The GU crew has teamed up with Hydrapak to design a soft-flask with a high-flow nozzle to make fueling for endurance events more convenient and less sticky. We love that it is reusable and helps reduce the litter trail associated with smaller single-serve packages.
Talk Nerdy To Me
This soft, reusable flask holds 5-servings of GU Energy Gel and features marks on the back help you measure your fuel. It's the perfect companion for GU's new larger 15-serving Energy Gel pouches.
