Product Description:

GU® ENERGY GEL FLASK 5.5 ounce :: Leave a lighter footprint while loving the convenience of the new GU® Energy Gel Flask 5.5 ounce. In efforts to solve the problem of empty gel packets cluttering the ground, GU® teamed up with their neighbors at Hydrapak to design a customized, reusable soft-flask. You'll not only appreciate the environmental advantages of the Energy Gel Flask, but you'll be psyched on the high-flow, twist-off nozzle, making fueling for long efforts more convenient and less sticky. Plus, the Energy Gel Flask is BPA free and PVC free, holds 5 servings of Energy Gel, and even has fill marks on the back to measure your fuel.

Features & Benefits:

  • Customized GU® soft-flask with a high-flow nozzle, perfect for fueling during long activities without the mess
  • Flask holds 5 servings of GU® Energy Gel
  • Markings on the back of the flask to measure your fuel
  • Fill it with 15-serving GU® Energy Gel and Roctane® Energy Gel
  • Made from durable plastic, BPA and PVC free

Used on this past marathon and it was great not having to open packages and no trash. Definitely will purchase again.


Love the convenience of multiple gel amounts in one place

Comments about GU Energy Gel Flask 5.5 ounce Gels Nutrition:

Love having one source, instead of multiple gel packets to store somewhere on my person. It's super easy to twist the cap and squeeze some gel into your mouth and then twist the cap back down. NO need to worry about packing out used sticky gel packets. The only downside I found was where to put it while running. I tried putting it in a side pocket on my running singlet, but the weight and bulk quickly drove me mad. I ended up putting it in the pocket of my hand bottle, but I then I had to stop to fish it out, take in my gel amount and then put it back. I do think it's going to be perfect for my long training rides though where I can put it in my bike jersey back pockets.
