Great for running

Love this! I use this in my running vest and it works really well. Doesn’t leak and is easy to clean. The straw was too long for where I like to wear it high up on my vest but I was easily able to cut it to the perfect length for me and fit the piece back on with no issues.

Great bottles for hikes or running

These worked out amazing for our hike. We wanted extra bottles for electrolytes. They worked perfect

Good quality

Great addition to son's collection and they were used in the cocodona 250. Perfect size, sturdy product and worked well for the race.

Does the job

They fit great in my hyrdation vest, but the lack of any rigidity makes them hard to fully dry after cleaning.

Great little bottle.

I use this for outdoor activity, where a full sized Camelbak would be inconvenient. I shoved this into a fanny pack recently during skiing. I noticed that the fanny pack got a little wet inside. I don't know if the bottle weeps through the cap, or through the drink nozzle. The plastic taste went away after rinsing a couple of times with plain water. I have also learned not to fill this completely to the brim, as closing the lid will always lead to some of that liquid spilling out.

I like it

I love this flasks its perfect. It is a little difficult to close, so make sure you push it really hard until it clicks. I havent had any trouble with it though, once clicked.

Not as advertised

Sent without the straws and now I cannot even return as I travelled out of country.

Great bottles!

I’ve used the bottles on all of my long distance runs with no problem, including my ultras, 50k, 50miles, 100miles with no issues! Easy to clean dry & use on the go!
