I love Hydroflask insulated bottles! They insulate and keep my drinks cool for hours at a time! I regularly use my hydroflask to bring iced water to and from work to stay hydrated and every time I go to take a sip, I can hear my ice cubs bouncing around! My water stays cold for hours (6+ hours) and always tastes refreshing in these hot summer months! I have multiple colors bc they’re all so cute, I can never pick just one! I also love that they’re very sturdy and can withstand some rough and tumble which still keeping its integrity. I would highly recommend this bottle if you’re looking to keep your cold drinks cold!!

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! 💦💦💦💦

I would recommend this water bottle as it keeps water cool. The earlier water bottles would not keep the water cold. On hot days, the water would get warm and the bottle would start stinking. Then it becomes very hard to remove the smell. I was skeptical on hydro flask and thought it was a hype. But now after buying this, I am hooked. Sometimes the brand products matter. The color is also very pleasing. It hasn't peeled so far. The other bottles, the paint peels

This excels at keeping beverages cold, and its leak-free design makes it incredibly easy to clean. My kids and I adore it – the vibrant color is a bonus, and it conveniently fits in the car cup holder. The only drawback is its weight; the little strap can make it challenging to carry for an extended period. Despite its overall durability, a well-placed drop can lead to breakage, as my daughter unfortunately discovered at school.

My husband bought me the hydroflask 18oz water bottle, which came with the original lid. I knew I wanted the straw to make drinking easier, so I tried a different brand which leaked (especially on planes) and the mouth piece cracked, so it made noise when I drank through it. I went though 2 of those with the same results? So decided to try this one. First impression was a good one! Well made, for the physique of the bottle much better, and even had a similar finish - definitely looked like it fit. It has a smaller profile, which I didn’t mind, but I think my husband would have trouble using the hole at eh top to carry around the bottle. There has been no leaking, no cracking and no noise!! My only complaint is that it’s a little difficult to pull up the spout ... MoreMy husband bought me the hydroflask 18oz water bottle, which came with the original lid.

My only complaint is that it’s a little difficult to pull up the spout without just touching the tip of it and pulling up. The small lip that is made to pull it open and push it closed is better for closing - seems to be at the wrong angle for opening.

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! :)

I absolutely love my Hydro Flask 21 oz Water Bottle! The insulation is top-notch, keeping my drinks cold for hours, even on hot days. The size is perfect for carrying around, and it fits easily in my bag. The design is sleek and stylish, and the build quality feels very durable. I also appreciate that it's BPA-free and eco-friendly. Overall, it's a fantastic water bottle that I highly recommend to anyone looking for a reliable and stylish hydration solution! Doesn’t spill and is simple to quickly clean!

I bought this Hydro flask water bottle for my daughter few years ago. It is very high quality bottle water. My daughter loves ice water, and one is great to keep the water cold all day. I usually fill the bottle with half ices and half water for her early in the morning, the next day, the ices are still there. I would recommend this bottle for anyone who would like to keep their water cold all day!

I absolutely love my hydroflask. I’m the type of person who only likes freezing cold water and my hydroflask will keep the ice in it for days sometimes. I have an alternate straw lid that I got on Amazon which I really like. The wide mouth makes it easy to clean. The handle makes it super easy to carry around. The only issue I’ve had is that I dropped mine in the garage which left a dent. This disrupted the insulation so it no longer stays as cold. I did find out that all hydroflask have a free warranty on them. If you go to the hydroflask website and submit a claim for a damaged bottle, they send you a new one! I really like this because I do have a tendency to drop my water bottle and bang it on things, so it’s good to know that I can always get a new one if I ... MoreI absolutely love my hydroflask.

I've been very happy with this bottle. After being hesitant to get a hydro flask due to the weight and diameter I finally pulled the trigger on this one after feeling the larger size in store and comparing the weight to my Nalgene bottle. The 21 oz size is a good balance of capacity for me and it fits in my backpack pocket, most car cupholders, and well in my hand during use. Dropped once on ceramic tile half full and it got a very slight dent that I have a hard time finding, so I'd call that a win. It's easily become my favorite daily go-to bottle and the color is great outdoors or in the office. I highly recommend it!
