Top Customer Reviews
I've already purchased 5 flasks (4 narrow mouth, 1 standard mouth) and recommend Hydro Flask to everyone I know, including strangers I meet at the gym or around the world as I travel.
I'm not ashamed of how many times I've thrown a Hydro Flask into my Amazon shopping cart.
I'm not even ashamed of how empty life felt after I lost my beloved orange Hydro Flask and had to return to work with a non-Hydro Flask water bottle (saddest, stupidest Monday ever).
I already wrote a rave review for the 24 oz. narrow mouth Hydro Flask; I purchased this 21 oz. standard mouth flask in Acai Purple for my mom.
Let me just say, Hydro Flask will always be my favorite thing ever.
HOWEVER, I've noticed the seller's product photos are way too bright, so if you're expecting to receive the exact color as the flasks shown in the photos, you miiiight be surprised.
I have Hydro Flasks in orange, pink, and purple - all of these are darker in real life than the seller's photos.
It's not a big deal to me (I LOVE my orange Hydro Flask) but for those expecting a certain color (the purple and pink seem to be way off) I've attached some photos so you know what to expect. :)
BOTTOM LINE: My life is now incomplete without Hydro Flask. BEST. THING. EVER.

Over time, heat loss occurs through the double stainless walls with a vacuum between them. However, most heat escapes due to poor design, location, and sealing of the lid and/or stopper. Specifically the lid or stopper should seal at or below the upper end of the double wall vacuum section of the stainless portion of the container and the lid/stopper should have some kind of insulation itself, if only an internal air space.
For instance the stainless steel Starbucks cup itself has pretty good insulation qualities on its own and the lid seals just at the upper end of the double wall vacuum section.Read more ›
The larger mouth size makes so you can fit ice in easy, and the size is perfect.
I use it for coffee in the morning, water all afternoon, and then my beverage of choice in the evening.
Warning: If you don't leave the cap off when you first get the coffee, the coffee will take a very very long time to cool down to drinking temperatures.
Yes they are expensive, but long term they are entirely worth it.
No more buying water bottles and having warm water,
no more wasting coffee cups and having cold coffee.
