Great as a Triathlon (or running race) Flask!
I am a Triathlete who does mostly Olympic and Half Ironman Distance races. I have bought a bunch of flasks trying to find the best for gels and liquids for my bike storage and a my TriSuit pockets. This is the best I have found. Size is great (fits all my trisuit pockets and my Tribike built in storage container). Great top (closes tightly/no leaking, easy to open with teeth and close), gets liquids out great. Slides in and out of pockets great. The only thing I would have changed is not having the base of it so firm (hard to squeeze out last bits of gels). However, compared sooo favorably to all others I tried. The rest had many flaws (too big, doesn't close well, hard to consume while running, material sticks/rather than slides into pockets etc). I have bought 8 of these so far and just ordered 6 more (want to make sure I have a bunch if they for some reason become unavailable.

Great little bottles!!
I’ve been using this for a few months now for small runs and larger runs. Specifically with 10 K runs it works really well with homemade liquid gel solutions to help you give you that boost of energy. Using it with a running vest works extraordinarily well as well as using it for 15k to 20 K runs will allow you to have extra juice to booster energy. Honestly, the price is a little bit expensive, but the usage is well worth the price.

Perfect Size
My go-to energy source! This is compact, convenient, durable yet easy to squeeze that has been flawless. The flow for my maple syrup is smooth, getting that quick energy I need in just a quick easy squeeze. The top pops into place securing it as I have not had it leak on me yet. This is right up my alley as an endurance athletic that I use for mtb, gravel, road and fat-biking. I could not ask for a better product that fits my needs and wants. Super easy to clean. For the price, it has paid for itself ten times over if I were to consistently use gels, such a great investment. Well worth the purchase!

Great gu substitute
These are the best for runs, instead of a gu. They work great.
