The GU Flask was designed in collaboration with the hydration-solutions experts at Hydrapak to make an easy-to-use reusable vessel for GU's assortment of ride gels. This soft flask makes contents easier to disperse than older hard flasks, and the high-flow nozzle is more convenient and less messy.

Holds 5 servings. Features printed measurement markings for convenient dosing.

Bought 2 of these to use for easier nutrition consumption. A great decision with no mess or trash to worry about during extending rides.

great concept, or so it first seems. But, alas, it appears impossible that ANYONE will figure out how to keep the fingers from getting sticky.

Other than the hard-to-loosen nozzle, the other serious downside is if you don't work thru the batch in your flask relatively fast, then the gel hardens in the flask corners and along the bottom edge. Short window to work through 5 packs' worth. So back to the individual eco-insensitive packs I go ,)

Hard to open

Be careful and don't over tighten! Extremely hard to get open to fill if cap is too tight. Otherwise a very good product. Very pliable and easy to squeeze. Has doseage marks. I like it better than the Hammer flask.
