The bottle is awesome, and with a sport cap you can't go wrong (which does fit this size by the way). I now have the coffee flask and the water flask and love them. Backcountry though delivered my gray flask with a huge black scuff on it that won't come off. It was a birthday gift so there was no time to return it, but just looks bad. I was embarrassed. Definitely doesn't look like I got it from a legitimate retailer.

Love this size when I'm not going on a big excursion. It's lighter and the perfect width for stuffing in a bag, side pocket or cup holder.

Hyrdo Flask really does a great job, by keeping Hot drinks hot for a few hours and ice for hot summer days. Always keeping the refreshments tasting great.

I had a 32 oz but it didn't fit in my new car's cup holder so I got this smaller one. I like the slim size it easily slides into small spaces in bags. I like it enough that I bought some for my parents and my kids! My daughter frequently comments how great it is that she can have cold water all day!

Great water bottle that is the perfect. size. Keeps ice throughout the day so you always have cold water in the hot sun. Also a perfect gift!! I have so many Hydro Flask products and love them all.

I have my 40 oz one and love it so I thought I'd get my mom and siblings their own (smaller size) for Xmas for their everyday needs. They love them. They'd never had a hydro before but now they won't go back!

Hydro Flask's claims that its bottles will keep cold drink cold for 24 hours aren't an exaggeration. If often put a drink with ice cubes in the bottle, and by the next morning some of the ice is still there. I've used several sizes of these bottles, and the 21-ounce size is my favorite. It is big enough to hold more than two cups, even with ice added, and the bottle is still an easy fit in my hands. And it's stable enough on my task that I have yet to knock it over. It's a great bottle!

You can’t go wrong with a hydro flask! I gave this to my girlfriends dad and he was very impressed with how long it keeps ice water cold. The lid is easy to screw on and off and the small handle is nice for carrying.

I gave this item as a gift, but I own several myself. I love these cups. They will keep a drink cold all day. They are great! Also, they have lots of colors to choose from.

I own numerous HydroFlask bottles, but none of them fit my car's cup holder, so I usually hear it rolling around the floor as I drive...Annoying. But, this size is perfect for keeping hydrated while driving. :-)

I own several Hydro flasks and the product couldn't be any better. I have one for hiking, work, the car and just everyday. I always have one to take on the go and it keeps my drinks cold or hot for several hours of the day. Definitely get yourself a Hydro flask if you don't have one already!

If you need an every day bottle that has to be insulated, then this is the one! I have various bottles from plastic, to non-insulated, to this one - insulated, and this is one of my faves. Buy this if you can handle the extra weight and you need to keep your things cold or hot!

I was unprepared for just how much I would love this bottle. I got the sport lid to go with it, all specifically for hot yoga, and this thing does not disappoint. I can fill it with ice and water, take it into a 92-degree room for 75 minutes, and at the end of it all there is still ice water in that bottle, and no puddle on the studio floor. I also love the bright yellow color, it's like it is happily reminding me to hydrate. Highly recommend!
