Reusable Gel Flask

I got some of these in 150 ml and 250 ml. They are great for fueling during long, long bike rides. I like to fill them with smoothies and other endurance slurries made from real food (e.g., banana date cashew, sweet potato quinoa sesame, etc.). You have to make sure the blended food is ultra smooth so that it doesn't clog the bite valve, but when it's smooth, these work fantastically! The bottle part itself is made of soft silicone and is a bit floppy when it's empty. That can make the 250 ml flask hard to put back into the rear pockets on a cycling jersey. the 150 ml size is small enough that that wasn't a problem. I saw other comments that the bite valves take some time to break in, but I didn't have that experience. They worked right away.

I hate all the trash associated with gels and weird sports fuel in general. These are amazing and did just what I hoped they would - provided an easy to use container for my real-food fuel. The opening to the bottle portion is wide enough to get a bottle brush inside of. The bite valve is a little trickier to get clean, but that's to be expected with real food. These can be used for more than just the gel mix.

I have been using the reusable gel flask for about a year and love the ease of use, versatility, and being able to make my own gel, not have any trash to deal with. I bought four more Flasks so I can have them when I go On rides 3+ hours or In an endurance race.

I love those flasks for the sole purpose that they are so easy to load and stuff in my pocket. I hate wasting plastic and single use wrapping. I like being able to tailor my mix to the concentration of CHO I need for a specific effort.

Super nice! Great materials. Easy to clean. Very happy.

A bit messy to get the powder in when mixing, otherwise works well.
