Rated 5 out of 5 by from Nice Bottle Bought this a week ago since I needed something more portable instead of the 32 oz wide mouth. It fits in the cup holder and in the side compartment of my backpack. Water stays cold for a good amount of time, I'm not really expecting something to be ice cold after an entire day nor would I let it just sit all day. If I have a water bottle, I'm drinking it as the day goes and if it's not ice cold anymore, I can always refill it.

Rated 5 out of 5 by from Where I am, my Hydro Flask is there too I purchased this about two months ago and am absolutely in love with it. I am the type of person who loves extremely chilled water after my runs. I throw in a couple of ice cubes and fill it up with water and by the time i get back from my long runs (6-7 miles), it is exactly what I need to quench my thirst. I literally don't go anywhere without my Hydro Flask.

Rated 3 out of 5 by from Great company, not the best tumbler I love hydroflask. I have a 32oz tumbler that I love so I thought I'd purchase a smaller one. I was so excited but I was a little disappointed. I'm a germ freak so this bothered me, the mouth piece that you drink from is always exposed! My hands touched it all day which grossed me out!! I'm a college student so I'm at school all day! By the end of the day I can only imagine how many germs I come in contact with. For that reason, I refurned this product.

Rated 5 out of 5 by from Lives up to its claims I bought this a few weeks ago and am very impressed so far. I took it out to the barn with me on a very hot day and the drink stayed cold even though the outside of the bottle felt warm.

Rated 5 out of 5 by from My daughter loves this bottle! We're now a complete Hydro Flask family! My wife and I got the 40oz wide mouth bottles and we decided to buy this 21oz sports bottle for our 8yr old daughter who is heavily into soccer. She was super excited, she fills it every day whether or not shes got soccer, and takes it everywhere she goes. It's the perfect size, works just as good as the larger bottles and we added the sports top to it as well.

Rated 1 out of 5 by from Where you put your mouth is exposed vs wide mouth which is covered I love my 32 oz wide mouth and decided to buy the 21 oz for a smaller option when needed. After drinking from it a few times, I realized that the silver part shown in the picture is where you put your mouth. This might not be a problem for some, but I don't like having the part touching my mouth exposed. In the wide mouth version, the part that touches your mouth is protected under the cover. I will be returning this and buying the 18 oz wide mouth.

Rated 5 out of 5 by from Best Insulated container I've ever had I have the 32oz version - put ice & coke in it before leaving for Disneyland - at the end of the day in 80+ degree heat there was still ice in it & the coke was still ice cold - I've NEVER had a drink container do that - not even a "Tervis" - GREAT JOB in doing your homework & designing a container og this quality.
