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

I bought 3 bottles for my family with 3 drinkcaps. The caps were nice and drip proof for couple of weeks. But recently one by one they started to drip a little to a lot now. Poor material and construction for the caps. Don't buy them if you put them in a bag or backpack. They will get everything wet.

I like, but get those little silicone boot thingy to put on the bottom of ur water bottle, cuz it gets damaged, the bottom. Plus it doesn't make as much noise when putting it somewhere. But my concern would have to be when I put ice in my bottle it melts quickly. Other than that the bottle is great!!

So far the flask does exactly what it says it will do, but I just don't understand why it's so much more expensive than other comparable items. It doesn't keep ice longer than other comparable bottles that I have bought. But I do like the sturdy construction and the lid with the handle.

i love my hydro flask. it keeps my water cool and they are super cute. but there is one issue. every time i drop it, it makes a noise. its not normal i dont think. it sounds like "sksksksksk" i dont know whats going on there but it must be fixed

good product and having good features ..............

its a great bottle and water stays warm but the cap does not covers the place where your mouth drinks and thats not very good for the hygiene i would very appreciate if you would do something with this information.

I was given this in the "Frost" colour (very pale blue that was renamed) for Christmas and I absolutely love it! It works so well and I take it with me everywhere! I especially love to take it on walks because normally you come back to the car and your water is hot and gross, but in the Hydro Flask, it is still ice cold! I was a little bit sceptical in the colour I chose but I am in love with it! It is the perfect colour and it looks exactly what it looked like on the website. I have noticed a few chips in the lid of the flask which is very disappointing, but nothing too dramatic that affects the usage. I would definitely buy this as a present for friends too because it is just so amazing. Overall I think that this product is awesome and one of my favourite presents that I got!

My granddaughter loves it. She uses it for school. She dropped it first day and put a dent in but she still loves it.

If you're on the fence between sixes, SIZE UP! There's nothing wrong with this bottle, I just wish I'd gone bigger.

My husband had received one of these for a gift about 6 years ago and we both loved it because it would keep our drinks fresh for hours even overnight. So when we decided to buy both of us a new one we were excited about it. We dont get to spend much money on ourselves lol. When they got here we both loved the colors we had picked out they are very vibrant. They also looked just like the old one they just have different lids. Well we have had them for about a week now and our drinks dont stay as fresh like they used to. Maybe its the different lids but we still want to use them because we loved our old one. They did get here very fast after we ordered them and they were in great shape when they came. I would definitely recommend them to our friends though because they are great for everything and every where you go.

I bought this for my daughter. The color is a vibrant watermelon pink and it's pretty lightweight. Water stayed cold for a while too! The downside is it dents quite easily hence the four star rating.

I'm happy with this product because it is welly built and is hard to break

i love it is keeps everything cool i love it definitly get it ]

I love the size of the bottle because it is the perfect size. It it just enough and not too heavy. I love everything about the size HOWEVER it doesn't come with a straw lid. I bought the sports cap but it just doesn't work like the straw lid.

I love this water bottle it keeps the water super cold and I love bringing it to workout but it fell off the stair machine at the gym and got a dent at the bottom and the paint chipped off, I was surprised how easy it dented :(

I bought this bottle in March 2018 (9ish months ago) and it was great. Not too big, not too small and it keeps my water hot/cold all day. My only complaint is how easily it dents and chips. I dropped this bottle only one time, and I have a huge dent on the top and two dents on the top. The bottle is always wobbling on flat surfaces because the bottle is no longer flat. The paint is also slightly chipped off where it was dented. The reason this is an issue is because my sister has dropped her water bottle many times and it has barely a scratch, and it was much cheaper than this Hydro. I guess I just expected more durability after paying so much for a water bottle.

I love the Hydro Flask. It really does keep my drink cold. I've been drinking more water ever since my daughter got me a Hydro Flask. Only thing I don't like is it dents and my daughter got an allergic reaction on her lip since she started using, she had to do the water fall so it doesn't touch her lips. She refuses to stop using it because she's used to drinking cold water, so I'll have to order the sport cap, maybe it'll help heal her lips. I hope they'll also offer for the standard mouths the straw with lid and hydro flip. For Hydro flip - with a handle too.

I Lovee this product but why is there no Mango color!!

Love this keeps my water cold, love the bright bold color, very functional and fun, I don't have to worry about leaving it out in the sunkeeps my water at the right temperature, perfect for all my outside adventures

My favorite thing about this flask is that it does a great job of keeping my drinks hot and cold. I drink a lot of coffee and it's nice to know if I come back to it later (mom life) that it will be the same temperature. The "grip" or texture of the bottle is perfect. It has a little bit of resistance so it isn't slippery even when wet, but does not feel tacky. My only wish, is that it was dishwasher safe.

Just to see how well and long the Hydro Flask kept a drink cold I filled it just over half way with ice cubes and nothing else. I waited 12 hours and opened it and poured just shy of an ounce of water out. I would say it works great, at least at keeping a drink cold.

This is a great flask to have. Screw top makes leaks nonexistent. The cobalt blue is a fantastic color. So far we have only used cold beverages which have held up great. Flask has sat outside in the sun during an hour long soccer practice and is still ice cold. Can't wait to use it for my coffee this winter

I like the Hydro flask water bottle. It kept my water cold for several hours. It is BPA free. I could easily grip the bottle with my sweaty hands. It is easy to hold. I did not like that you have to keep opening the top to have something to drink. The bottle was easy to hold. It is a good size weight. I would definitely recommend this product to people, especially if you want to keep your drink cold. It says that it keeps hot drinks hot, but I did not put any hot beverages in the bottle. This water bottle is good for people of all ages and boys/men and girls/women. It is hard to use it while exercising because you have to stop exercising to open the bottle and then twist the top back on. I like the grip/holder on top. It is convenient. It is a good bottle to have when hiking, camping, or sight-seeing for several hours.

This Hydro Flask keeps liquids hot for hours. Nice for coffee or tea at your desk. Also nice to put cold drinks in for the afternoon. The size is just right to take with you. Stainless steel interior is easy to clean.

Was pleasantly surprised to see how well this bottle keeps things cold. If you are into camping or hiking this is the bottle for you. haven't tried any hot beverages yet. I suspect it will work just as well
