Introducing the new 15-Serving GU Energy Gel pouches. GU ‘bulked up’ their proven Energy Gels into a larger serving size to give you more ways to fuel while training and racing. Loose trash and sticky pockets are hard to avoid when you're out on the trail or road for hours and hours. That’s why GU partnered with HydraPak to create a custom 5-serving flask and nozzle designed specifically for GU energy gels. The flask makes it easy to carry the fuel you need while reducing trail-litter along the way. Less-mess, less-litter, more Energy Gel!
