• i have a variation of these that I bought to use for a home made gel I was trying a few years ago, the ones I have are food safe, and work well for energy gels if I want to carry a few at once.

    I think high 5 do a specific gel flask as well, but don't know how big it is... if you are taking a drink it might be easier to just use an energy drink...

    It's worth trying a few different brands to find one that you like the taste of, they range in consistency and content (high 5 are about 20g of carb and fairly watery, torq ones are exactly 30g, whereas zipvit ones are 56g) and its worth training with them as you'll get used to the taste as well as training your gut to deal with them.
