Great Water bottle

My wife and I received our water bottles about 6 years ago, and love them. We upgraded to the straw lids (several of the old style failed, as the little O-Ring on top would degrade. Luckily Customer Service is some of the best in the industry, and replacements were always sent out! We recently upgraded to the new style, and they seem engineered better). Whether keeping coffee warm when its below freezing, or water cold on 100 degree days, these water bottles are great. I wish they would fit in out vehicles cup holders, which is the only downside. They do dent easily, but we purchased the bottom silicone protectors, which have saved us several times.

Great water bottle

I've had this water bottle for about 5 months now and it has lived up to the hype and expense. I'm very pleased at how it's able to keep water cool all day even when the outside of the bottle is hot, the water inside is still nice and cool. The only downsides of these bottles are that they are heavy and a bit pricey. I however find the weight to not be a deal breaker and if the bottle last for a least a decade then it was probably a good investment.

Amazing thermal insulation!

This is, without a doubt, the best water bottle that I have ever used. The wide mouth allows you to add ice cubes, sliced fruit, or whatever else you desire to your water, and the top screws on tightly so you can bring it anywhere with you without worrying about spills. The flexible silicone handle also makes it easy to carry around in your hand, although I would probably recommend getting a bottle sling if you want to attach it to a bike or something. For such a huge capacity, the size really isn't that bulky, and the fact that you don't need to refill very often makes it super convenient and simple to stay hydrated. However, what really amazed me about the HydroFlask was how well it insulates my drinks! I can throw in a few ice cubes, fill it up the rest of the way, and the liquid inside will stay cold for hours as long as the lid is screwed on. I've tested it by leaving it at room temperature for over twelve hours, and there was still frozen ice inside when I checked. The only downside I've noticed is that if you fill it up too much and there is a lot of ice inside, a vacuum somehow forms inside the bottle that makes the lid very difficult to unscrew. I'm not sure how or why this happens, but it probably has something to do with the air at the top of the bottle becoming denser at a lower temperature. That said, it's not that difficult to avoid, and the fact that it happens at all is a great testimony to how tight the seal on this bottle is. Grab one, you won't regret it!

Perfect size for the classroom.

Needed a water bottle that would keep my water cold and that I didn't need to refill often. The 40oz keeps me from leaving my classroom multiple times a day to refill or replace the ice.

Amazing Quality

Finally found an insulated bottle that keeps my water cold even when sitting in the sun all day. I am a river guide and haven't been able to find a water bottle that can keep my water cold UNTIL NOW. Thank you Hydro Flask! Also very durable. It gets tossed around in the boat and at camp. I love this bottle!!!

Love the color and size!

I've been using this bottle for a couple months now and so far I love it! My only issue is that is doesn't seem to keep ice for very long. I'll fill it halfway to almost full with ice and in an hour the ice will be completely melted. So disappointing! The water does stay cold but not ice cold as I prefer it. I wonder if a smaller size would be better with holding ice? I do love the Pacific color and the durability!

Good Water Bottle but dented

Hydro flask was dented in two places when it arrived. The color is as expected. Holds temperature for long periods of time. Would give it a 5 star rating had it not been dented.

Not good for coffee

I?m a truck driver who likes to have hot coffee. I was told this was the best. After 6 hours coffee is lukewarm. Works good for cold beverages

I bought this a couple months ago and it?s the perfect size. It stays cold all day long. I?m a teacher and I barely have any time to go fill up water. I love having it and I will always have one on hand! It?s definitely worth the money! Not to mention the colors are all amazing!!!

Love my Wide Mouth

This flask works really well. Last summer I worked at a fruit stand with +95F temperatures with light shade. The beverage staid cool for several hours before starting to get warm, that's without ice. Very happy with capacity. An 8 hour shift with a standard water bottle I would have to refill 8-10 times, yes I'm a camel. But not I only need to refill 3-4 times. Got the Sunflower I love yellow great color.

Great features!

I bought this about two years ago and still love it. I did dent a bit shortly after but that's my fault. Still works great and I like that it holds a large amount of water. I've used it daily since I bought it and still do. It's kind of expensive for a bottle, but I think it's worth it for the quality. Two years later and it still looks new minus the dent. Since I have got it, I think I have been drinking more water and that is always good. I would like a new one and I'd like it in red. As of this review they don't offer it in red in the 40 ounce so hopefully soon because I will get it.

Loved it!

I am a very active person and am constantly hydrating to keep myself healthy. I play soccer so I have to have plenty of water in my system for practices and games. I also enjoy many outdoor activities such as hiking, paddle boarding, boating, camping, swimming, and skiing. For all of these activities I need cool water available at all times, especially for the ones that are completed in the heat of summer. When I am outdoors and being active I don't always have access to clean water to refill my water bottle, so it is imperative that I am able to carry enough water to keep hydrated. I am going to be reviewing Hydro Flasks, but specifically the 40 oz Hibiscus colored Hydro Flask. Having a 40 oz Hydro Flask makes it so I don't have to constantly worry about refilling my water bottle, at least for a few hours. I can?t stand it when my water gets hot or when I run out of water in general. I can't drink water if it isn't cold, it just doesn't taste good to me. With a Hydro Flask I never have that problem. If I put ice into my Hydro Flask it keeps my water cold for the whole day and often times even into the next day. Women are supposed to drink 2.7 liters of water a day which converts to 91.2979 ounces. That means you would only need to fill up a 40 oz Hydro Flask 3 times a day. Men are supposed to drink 3.7 liters of water a day which converts to 125.112 ounces. That means they would only have to fill up a 40 oz Hydro Flask 4 times a day. Hydro Flasks are also available in a 24 oz, 32 oz, and even a 64 oz model. With a 65 oz Hydro Flask men or women would only have to fill up their hydro flasks twice a day. Not only do Hydro Flasks make water bottles to keep you hydrated but they also make tumblers and mugs to keep your hot drinks hot. They are constantly coming out with new colors to choose from as well. Right now their colors are black, white, stone, olive, cobalt, pacific, alpine, carnation, pineapple, fog, watermelon, hibiscus, sunflower, and spearmint. I started using a Hydro Flask when one of my teammates acquired one. She would rave over her new water bottle and how it always keeps her water cold during the hottest practices. After a while I decided to take the leap and purchase a Hydro Flask myself. The new water bottle lived up to all the hype and it definitely exceeded my expectations. Hydro Flasks pros definitely outweigh the cons. Such as being insulated to keep your drink at the desired temperature, and a variety of sizes and colors you can pick from. The major con to the Hydro Flask product is how easily they dent and scratch. If you are clumsy like myself and drop things constantly, your Hydro Flask will likely have a few bumps and bruises on it. Overall, I think everyone needs a Hydro Flask for their day to day use no matter what that entails.

Absolutely Wonderful!

I bought this last week & have been very anxious for the delivery. Finally received it this morning & my life has changed! I no longer have to use plastic bottles, or have to keep refilling my cups. Infilled up my Hydro Flask at 9, it is currently about to be 3 & my water is still icy cold! Super excited for the future with my Hydro Flask : Also, let me take a minute to appreciate the packaging! Everything was plastic free, I received a cardboard box with paper wrapping and it is absolutely beautiful! It makes me want to buy another Hydro Flask in order to receive another plastic-free package!

An absolutely incredible product

I am someone who drinks a LOT of water, especially since I don't drink soda or coffee. As much as I love my 64oz HydroFlask, I don't always end up drinking the entire amount when I'm out and about, and by the time I use my water bottle again, the water inside is not good. So I got a 40oz bottle so I can drink all or most of the water I fill it with, leaving room for possible refills. I got a custom bottle and it is PERFECT. I am so freaking happy with this water bottle that I could skip. It's a perfect size for mid size trips or if I am in a location where I can comfortably refill my water bottle regularly. Again I love my growler but sometimes it's too much and this water bottle is a great addition to my collection, as well as being a great size for when my other water bottle is too much. Never thought I'd have more than one water bottle but this was a fantastic decision and a fantastic product!

Love!!

I bought this 40oz hydro to replace my 21oz and I'm obsessed! I drink so much water and had to fill my other bottle up so much throughout the day that I decided it was time to size up, and I'm so glad I did. Now, I don't have to try and find a water fountain on campus or run back to my dorm in between classes to fill up, I'm good for a few hours. I highly recommend also purchasing a straw lid, it makes it super convenient to drink when walking, driving, or trying to be quiet in the middle of lecture.

Best Bottle Ever!!!

I bought 2 of these several years ago. Unfortunately, they got misplaced when I moved. I finally put my hands on one of them and began using it. I have NEVER been so impressed with a product. I filled it with ice and water at 6 PM last night. It is now approximately 1 PM the next day. I was shocked that the ice was still intact, so I took a sip. Cold enough to give me a brain freeze. 19 hours later!!! You totally need this bottle!!!

My daily go-to

This bottle did an incredible job until the bitter end. I used it daily for all hydration activities whether it was working at my desk to hikes and river trips. My bottle met it's untimely demise after being stuck on a raft that was pinned against a boulder. I will be purchasing another one this morning.

40oz bottle

By Dnav

I've been a fan of Hydroflask for a decade now but these 40oz bottles have been the greatest addition to any pack. I've used it as I was a wildland firefighter perfect size to carry on the fire line. And I also use it now working on an ambulance as a paramedic it fits right into the built in cup holders. Holds ice for over 24hrs. The different attachments make it more adaptable to any situation. I like the straw lid since I'm always on the move I dont have to worry about trying to drink while...
