This Water Bottle is made from 18/8 food-grade stainless steel and the amazing double wall vacuum insulation gives it top notch insulation power, keeping cold liquids icy
cold for up to 24 hours!! It’s truly amazing! My hot liquids are actually staying steaming hot for up to 12 hours. The TempShieldTM cuts any chances of having any
condensation all while it keeps beverages icy cold. Grandma got this for my oldest daughter who is at band camp in July. It keeps cold and gives her 21 oz of hydration while
out in the sun for hours with her band mates. Grandma found a real winner with the hydro flask! This is 10/10 great.... Show more

My boyfriend and I are both obsessed with these cups. We both drink a ton of water, so keeping our drinks cold at all times is great needed. These rarely leak, which is also
great. Water bottles of all kinds that leak are a pain quite pointless to me!! We love allll the colors especially white, pink the pretty blue ones with the pink logo. They have
really stepped out of the box creativity wise with the colors. Yay! 🌈🌈🌈 This is a high quality water bottle that will last you for a long while! I highly recommend! 💦💦💦💦... Show more

Hydro flask is my go to brand for reusable bottles, I am really impressed with the quality of their products. This bottle is so light weight compared to other bottles I own from them. It’s also very durable too. The slim design makes it very travel friendly and the standard mouth opening makes it very easy to drink out of. Perfect to use during any outdoor adventure. I know from experience that hydro flasks bottles keep beverages at the perfect temperature. It keeps cold liquids very cold for a long time. Also if you have a hot beverage the bottle is insulated very well to keep the liquid piping hot. The cap has a great seal to keep liquid at the perfect temperature and to prevent any leaks. The cap also has a strap attached so carrying the bottle is very easy. I ... MoreHydro flask is my go to brand for reusable bottles, I am really impressed with the quality of their products.

Really Accessible and Great Quality! My Hydro Flask is the best water bottle I have ever had. With all the different colors and sizes to choose from, I had an easy time finding the one I liked most. They are easy to take with you wherever you go as well. Personalization wise, they are very good with stickers. You can put on whatever stickers you want to make it more personal to you. I have put stickers on mine and none of them are even close to coming off. Just make sure when you put one on, you want it on for good. Another thing I like is how there are many different types of lids that you can use and switch out whenever you want.

I have been staying hydrated ever since I got my Hydro Flask because I can carry water with me everywhere I go. The accessibility of a Hydro Flask is just what anyone would need in a water bottle. Most Hydro Flasks range from 30-50 dollars. Which to me, is quite a lot for something you are just going to be putting water in. But let me tell you now, it is worth the money. In the mornings, when I put water and ice in my Hydro Flask, I can leave it somewhere for the whole day and when I come back for it, the ice is still there. Or when it is cold and I’m wanting some hot chocolate, I could bring it in my Hydro Flask and it would stay warm for a really long period of time. None of my other water bottles or containers can do that. The Hydro Flask that I have now has lasted me 3 years and is still in almost perfect condition. The only reason it wouldn’t be in perfect condition is because I drop it every once in a while and it has some scratches and a couple dents. If I was more careful, it would look brand new. Hydro Flasks are definitely worth the money and I would recommend everyone get one.... Show more

This water bottle is wonderful for any trip or day hike or even a trip to Disneyland to stay hydrated throughout your day. My husband I love our Hydro Flasks. With the standard mouth piece it’s easy to drink the insulated bottle keeps your colds cold hot liquids warm. Love having this in the 21oz because it fits into every bottle holder that you find on standard backpacks or you can even use a carabiner (that’s what we do with our 32 oz version). Convenient essential tool that we go nowhere without. Comes in such pretty colors like bright teal, Lavender purple. It’s a plain color design with a satin finish that you can even decorate personalize with your own stickers. Love these will continue to add more to our collection.... Show more

The standard for keeping drinks cold or hot! I bought a hydroflask early on after not being super impressed by some of the bigger name brand competition.. our cups/bottles, etc were not holding up and had chipped paint around the rims, wonky bottoms, etc. After using about 5 different hydroflasks in various colors in very heavy use (daily by multiple people each using one) I can say these live up to the hype! No chipped paint, drinks remain ice cold- overnight! In fact, we’ve left them in the car in the AZ summer heat (by accident) and somehow only had melted ice but still, cold water when I went to dump it out 14-16hrs? later. That’s the best test we could give them aside from taking our daily dose of living abuse.. And I’ve also found coffee is also crazy hot in ... MoreThe standard for keeping drinks cold or hot!

And I’ve also found coffee is also crazy hot in the smaller ones after hours, so be careful! :) I was not expecting them to work as well, as a mom I’d become used to luke warm coffee whilst running around in the morning, now I use one of these and get normal coffee- aka HOT! We recommend! :)... Show more

This water bottle was okay… not great. I received this water bottle in 2020, at the height of the Hydroflask craze. The thermos quality on this is not great, ice melts in the bottle just like it would in any other water bottle. The durability is good, it takes quite a few hits to dent the bottle. The paint also chips after some time, as well as the logo. I did have to get rid of mine a few months ago, as bottom started to leak. Overall, the Hydroflask is fairly durable, but doesn’t quite live up to the hype and there are definitely more durable and overall better water bottles on the market.... Show more

Great insulation but SOOOO fragile

16 August 2021

I have purchased 4 Hydro Flask products -- a 21 oz bottle, a 20 oz coffee mug, and two 10 oz wine tumblers. All of them have dented almost like they were cardboard. The bottle was bumped off a counter at work, fell about a foot and a half to the floor, and the dent creased the exterior and ruined the insulation factor.So I got a coffee mug and a bottle boot (along with the wine tumblers), because the insulation is great. The bottle boot helped, but it again fell at work (same distance); the boot made it bounce, but it still sustained a dent so deep it wouldn't stand upright on it's own. The boot helped it stay up, but the mug became more unstable, fell over at work again, and sustained another deep dent. It just wobbles now.And recently one of the wine tumblers ...

Considering the Hydro Flask products are meant to be outdoors items (which I got them for as well as work), you'd expect something more durable for the premium price.... Show more

Misleading, Confusing Website Listing

13 December 2022

I ordered two of these bottles.First, the listing is confusing. It says you can “choose” the lid you want. NO. You can **separately BUY** the lid you want. The cap you get is one you have to remove in order to drink from the bottle. If you want a cap with a straw or sipping option, you have to order a completely different lid separately.Pros—24 oz is exactly the amount of water I wanted in a bottle—The fit in car cup holders—The seem sturdy, well made—They look greatCons—I wish the bottles were slightly wider and a bit shorter. I want them for my car cupholder, and while they fit, there’s room left over and they are so tall, they interfere with the car’s heat/AC controls, etc.—The next bigger size bottle won’t fit in the cup holders—The flex cap ...
