## Customer Reviews

### ⭐⭐⭐⭐⭐ GREAT PRODUCT
*by G***Y on August 17, 2025*

This is the third bottle like this I have gotten from them. The other kind is the one with the hand loop on it, effective but annoying to me. This is better! I bought a vest with a similar water bottle but it was so hard to get the water out. The water comes out so easily with this one and it is leak proof, very durable, and the material does not alter the taste of the liquid. The size is good at 17 ounces, I wish it was an even 20 though. No issues at all while running with it or drinking from it while running. A definite recommend!

### ⭐⭐⭐⭐⭐ High quality flask
*by J***Y on June 2, 2025*

Great lightweight high quality water bottle. I love the easy fill option and it is easy to clean. The perfect capacity for a flask. Fits in my ultimate direction race vest perfectly.

### ⭐⭐⭐⭐ Quality flasks, but big for Salomon vests
*by M***K on July 29, 2025*

Bottles are great, just don’t fit Salomon front pockets well, but to wide
