Fuel efficient.

GU's flavorful ride gels are incredibly convenient and delicious in themselves, but we've all experienced how troublesome they can be to open, extract, and stow away. Well no more sticky hands and littering with GU's redesigned flask, created in collaboration with the experts at Hydrapak. Its soft design takes less effort to get the gel where you want it, helped along by the high-flow nozzle that's also less messy than traditional designs. It even features printed hash marks so you can measure out your nutrition over the course of your ride.

Holds 5 servings.

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 ,)

Have used several times on my training rides. I make my own GU. Issue for me is that it is not easy to use one-handed. Taking two hands presents some additional risks while cycling. Furthermore a few times the entire top rotated, vs just the spout. Thus I will continue to use on training rides but in other rides will likely continue to use the packets that I can open with my teeth.

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

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.
