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, fuel with it, and reuse it!

Handy Dandy

I love this thing! It's cost effective, produces less waste, and really convenient. It's nice that if you only need a tiny bit, you can close it back up, whereas with the individual packets, if you don't finish the whole thing and want to save it it, it can get pretty sticky!

Easy efficient energy at any moment

This is the easiest method to consumer GU! Opens easy...squeezes easy...easy to get out of a back jersey pocket...cleans easy...just easy easy. And no trash! Definitely holds more than 5 servings (I can fit 7 servings in a flask - which is great for long rides). No fuss, no mess!

Perfect Solution for Gels

I started using the GU Flask for mountain bike races this past year, and it was a game changer. So much easier to pull that out of the jersey pocket, open with your mouth, get your gel, and put it back in the pocket. Eliminates the hassle of multiple packets in your jersey, trying to get the trash back in your pocket, and getting your jersey all sticky. My go to is the Sea Salt Roctane.

No more drops

Sometimes during a group ride, say at a traffic light, I'd fumble to finish a packet of Gu. The light changes and I'm still fumbling around. Before I know It I'm chasing as the boys ride off! The Gu Energy Flask solved that problem - no more Gu break drops!

Love it

I purchased one of these for a race this past weekend and was very happy with it. I have to be honest, I am not a fan of GU brand gel, but rather, used Hammer Gel in it. It worked like a charm. No mess, no garbage, and easily stowed in one of my hydration pack chest pockets. I have already recommended it to a few trail running friends.
