Energy Flasks

I really like these. I like the firm form which makes it easier to identify & pull from my jersey pocket while riding and the nice, wide opening at the top for creating my own energy drink-(gu-like)-concoctions. Easy enough to clean as well. The only drawback is that the flask is so smooth I lost one sliding out of my jersey pocket on a little bumpy portion of my ride-which was a rode/tarmac (not gravel or mountain) trail; so now I am down to 3 flasks. But I would certainly recommend to anyone.

Exactly what I needed. Perfect size and easy to use and wash.

I mostly use these when I go out on my longer rides (2+ hours). I’m also starting to bring them hiking and running - they are the perfect size. I’ll probably bring one or two when I go skiing this winter too. They are a little smaller than some of the other bottles and soft flasks I’ve tried, which makes them better for what I need. I just fill them at home before my ride with a few energy gels and a little water to make it more drinkable. Then I put them in my jersey pockets, or in my hip pack when out mountain biking. I’m also looking forward to experimenting with my own DIY gel to save a little money. I don’t miss the days of carrying around sticky garbage, that’s for sure. Overall, I really like these flasks. And they are really EASY TO WASH! I just use soap and water under the sink, but sometimes I put them on the top rack of the dishwasher. Highly recommended!

Love my flasks

Using gels wrapped up in individual packets is so old school, producing tons of litter and sticky messes. Aside from a environmentally friendly alternative these flasks let me dial in my nutrition by coming up with my own recipes. Think maple syrup and freshly brewed coffee for a energy boost or mix in your favorite carbohydrate powders with some electrolytes for all day fueling. The size of these flasks are perfect to throw in your jersey pocket and the nozzle makes it super convenient to fuel on the go.
