My daily companion 👍

This bottle is amazing! This is my second HydroFlask, I have a larger 40 oz but it doesn’t fit in my backpack, so I decided to get the 21oz bottle because it not that heavy to carry it on my backpack all day along my laptop and other necessities. No spill at all, mind you, this bottle is inside my backpack with my laptop all day and never had an accident! And the best part is that I walk everywhere hands free 🙌 no tumblers to carry around and no spilling water everywhere 🫶

One of the best bottles I have tried so far

Reasonable price for really good quality. Over years I have tried so many bottles due to having kids :) this is by far the best quality and holds cold for 10h even ice inside won’t melt if you put too much :)

Hydro dollars

Good product. Shipped quickly. Hydroflasks are a bit expensive but probably worth it.

Love it !

The media could not be loaded. Needed a smaller bottle because I was tired of carrying around the big one at work. Love itttt.

Great bottle through and through

Great bottle... keeps drinks cool or hot depending on your needs. For how long? Have no idea, never timed it. However if I fill the bottle in the early morning by mid morning it it still pleasantly fresh. The flex cap is awesome to carry around and the bottle is robust and feels like made of really good material. It's easily washed in the dishwasher and up to now the color stayed perfect.
