Customer Reviews Hydro Flask 21 oz Standard Mouth with Standard Flex Cap

Actually does keep stuff cold. I left it in my car with ice in it to test it. Came back the next day and I still had ice in it. great product. only problem is i wish it came with a sports cap to make it easier to drink.

#Tryit......For many years I have used aluminum water bottles ... but it is really specifically I have loved it. Hidro-Flask is made of stainless steel, very practical and functional, its mouth design is very comfortable to drink .. It has an isolated design that works perfectly well. I have often been very surprised to see that after several hours the water still remains cold. I am really satisfied with my bottle because it exceeded my expectations and has been very useful on the days of scorching heat. I recommend it 100%. Nothing negative to say .

The hydro flask is amazing! I have a Yeti that I was using everyday. I tried the hydro flask for the first time and I love it! It keeps my drinks colder than the yeti does! I had ice in it for a full day. I refill several times a day at work with water and still had ice when I went to bed! I will definitely be purchasing another one.

One thing I love is a cold beverage and this flask keeps my drinks nice and cold throughout the day. This has come in handy while running errands lately due to the weather being so hot. I also like the size as it is just right for me.

I used my flask and put it to the test. I filled my flask with tap water and ice cubes; then I was off to the gym. At the gym, the water was ice cold and the ice cubes were still intact. I used it the next day for a long 12 hour work day and had the same positive results. The flask has a great weigh, is easy to grasp and is very sturdy. I highly recommend this flask.

This was sent to me free to review, and this is my honest opinion. I'm very pleased with the quality of this bottle. I've tried it with both hot and cold liquids, and it works great with both. I tend to use it more with hot coffee or tea, and I'm incredibly happy with how perfectly hot my drinks stay for hours. On a purely cosmetic level, I think it looks sleek and modern. It has a good amount of heft to it, so it doesn't feel flimsy, but it's not too heavy to carry either. Overall I'm very happy with this product.

Awesome bottle. High quality, keeps drinks extremely cold and can take a pounding. Lid seals tight and you has a hook to attach if needed. Overall high quality product and I am very happy with it so far

This Hydro Flask water bottle has met all of my expectations. It keeps my drink cold for a long time. Love the color and design. It is a great size for carrying around all day. It fits well in standard cup holders. I would definitely recommend this product to my friends.

This is the perfect size flask, and the color is just beautiful. It keeps cold drinks cold and hot drinks hot for a long time. The only thing I would do to improve it would be to have an easy way to hang onto it, such as a grip pad

I received this product in exchange for my honest review. I'm in love with this Hydro Flask. I love that it keeps cold liquids cold for hours and hot liquids hot for hours. I am so glad I got this,so handy. I recommend for everyone to get this product.

Hydro Flask 21 oz Standard Mouth - White. I was able to try this out and absolutely like it, keeps my water cold while I'm out walking. It also keeps the coffee nice and hot, just like you poured it after it brewed. It has a nice grip and lid is easy to take off and put back on. Recommend highly!

I really like my Hydro Flask 21 oz Standard Mouth - Cobalt. I filled it with water and had it in my hot vehicle for most of the day and it was still cold when I went to drink it. I don't drink hot stuff, so I am not sure about it keeping it hot. I definitely recommend this product.

So far this bottle has worked great! It has a sleek look to it, making the sizing perfect for me. Very vibrant blue color and is stainless steel. I've left this in the car a few times so far and have came back 5+ hours later with ice still in it and it still being drinkable, I haven't had the chance to try it in the car much longer than that yet! I haven't tried anything hot in it yet, either, but I feel like it'd work wonders! I'd like to add that I live where it has been 90+ degrees and it has held up great for keeping things cold so far! I am happy with the bottle!

I just love the color. I took it to work with me cause i work 3rd shift and always need cold water to keep me awake. This kept my water cold in the hot shop way longer then i thought ever could happen. Even ice packs dont last long in my shop. It holds alot too what is really nice. I love it. No spills doesnt leak. Its amazing.

I love my bottle I use it every day in this Texas heat! I hope that one day Hydro Flask releases a periwinkle color because that would combine my two favorite things!

I bought one a couple weeks ago and there amazing. I love how they keep your stuff cold or hot.

Got mine right before moving to Colorado and it has served me so well for hiking, camping, road trips, and festivals. It's so durable and even survived getting run over by our SUV. It's also considerably reduced the amount of plastic water bottles. Win win all around.

I have now bought 2 of these. My son has bought 2 & my husband 2 as well. My son's girlfriend has 1 or 2 & we convinced a family friend to get one. EVERY single one of us is EXTREMELY Happy with our Hydro's! I don't know how I survived without them!!!

These work wonderfully!! Left sitting in my hot car and hours later still had ice in the bottle. They are too good to be true! Totally worth the cost!

I bought this Hydro Flask yesterday and I love it so much. I got the 21oz Flamingo bottle. It is amazing.

I bought a Hydro flask last year in Canada and loved it. I just bought the normal cap and not the drinking cap which I bought later when back in the UK. You need to use the appropriate lid as the drinking lid air hole can become blocked if milk or something sugary is put into the flask. On a normal day I fill the flask with water, add a few ice cubes and you can hear them clanking around inside many hours later. Really like the product, works well, is easy to carry. I've not used it with hot liquids as I'm not sure how easy it is to drink from. All in all after daily use for a year I'd have another in a heartbeat.

My reasons for loving this bottle: 1. Not a day goes by that I don't use at one of these bottles for water, tea, and food ... I have multiple bottles, in several sizes, so feel qualified to write a review. 2. The outside of the bottle feels good to the touch ... good temperature for my hands, feels smooth against my skin. This might sound strange, but this matters to me. The bottle never, ever gets condensation on it, even in the hottest east coast weather. When I have hot drinks in a bottle, the outside doesn't get hot to the touch. 3. Sometimes I drink from the bottle itself, and sometimes I use the spout ... my experiences with both methods have been positive. 4. My drinks taste just like they are supposed to ... just the drink! There is no taste from the inside of the bottle that leeches into my drinks. 5. There is nothing on these bottles that can break if you accidentally drop them. I have accidentally dropped other bottles from big box stores, only to be disappointed that the spouts break ... and back to the store I went to get a new bottle. No more wasting time and money now that I've found these gems! 6. Because of how this bottle is manufactured, there is maximum volume on the inside for your drinks as compared to bottles that can be purchased at big box stores. 7. My family and friends have received these bottles as gifts and have given them rave reviews. 8. I anticipate having my bottles for life ... worth the investment because they will surely last.

I have had a 21 oz. hydro flask with a sport cap for about 5 years. I have noticed that my bottle is leaking from the lid. It seems hat the o ring has worn and is not holding liqiuds from leaking. Dudes your life time warranty cover leaky sports lid? I use your flask 5x a week.

I love this water bottle! I've had it for over a year and I'm going to buy a new one, not because the other one stopped working. The color is great, the paint doesn't chip even when you drop it. If you're lucky when you drop it it won't dent. It keeps the cold liquids in and it's great.
