Absolutely love it! Took this on a 4 night hike, and it held just enough for me to have a few drinks every night. It is very light in comparison to metal flasks, also super sturdy and leak proof. A perfect hiking companion. I really really like this product. 100% recommended!

Useful flask, however cap doesn’t entirely clear filler when unscrewed so you have to drink slightly offset. Other than that, very good.
