Mom loves it!
Great color, does its job well, this is a replacement for my mom’s older hydroflask which has served its purpose for almost 10yrs! These things last long. And I got it at a discounted price too.

Keeps products cold or hot
Little on the pricey side like they say you get what you pay for absolute quality product did not mind paying the money for the quality...

Keeps water cold a long time
The right size for the car. A pleasure to drink from the rounded lip, but it takes two hands to open the bottle -- a tradeoff I'm willing to live with.

This should be your go to drink container!
Excellent durability, keeps the beverage cold for a very long time! I actually downsized from the 64oz and am very, very happy with this one!

Quality water bottle
My daughter asked me to buy this bottle, because so many of her friends have it. It's pricy but I guess this is very trendy water bottle, and she absolutely loves it. Got another small kids version for my other kid.
