I received this about a week ago. I filled it with ice and water. I sipped at it for 2 days and I still had ice!! I couldn't believe it. This is fantastic! I need to get another one for my daughter!!!

The hydro flask has been a great addition to my coffee and wine collection since keeps my drinks hot or cold for the perfect duration of time. I've referred my friends to the product and they are unhappy they were not able to try to product for free as well.

This flask has a super tight seal. It is very well made and keeps your liquids hot or cold for a long time It is likewise very easy to clean. I highly recommend it for anybody who wants to drink hot coffee or tea throughout the day.

I received The Hydro Flask a couple of day ago and I loved it!! The comfort grip was great, and it kept my hot coffee hot, but the outside wasn't so it was easy to handle. Also kept my cold drinks very cold for long periods of time. It is very stylish looking and has a lifetime warranty. I would definitely recommend Hydro Flask for anyone that takes drinks on the go!!

This bottle is top notch. It feels good on the grip, doesnt get slippery on hot days and you have sweaty palms. It keeps everything hot and cold forever. It closes well and doesn't leak. What's there not to like? Easy to clean and not all the heavy given its quality.

I seriously love this flask! I put ice water in it in the morning and it's still as cold at night. I also like the textured feel and the vibrant color I only wish the handle on the lid was removable so I could hook it to my back pack.

The Hydro Flask 21 is a great bottle to carry around with you. It keep your drink cold for as long as it is in the container. It fits in the side compartment of my backpack and also in the cup holder in car.

This is better than other drink Carrie's. This one has a strap that makes carrying it so much easier It keeps your cold drinks colder longer and your hot drinks hotter longer. I love how it looks and feels better then others.

I love the look and color choices available for this flask it keeps my drink nice and cold for hours or my hot things nice and hot I absolutely love it. It can be used on the go I usually just put it into my purse no issues with spills and it is very durable could also carry on the side of backpack or on a bicycle

I love this hydro flask for many reasons. It keeps your drink cold for a long period of time and the bottle doesn't sweat. The handle on the cap makes it easy to grab and go although I wish it had a flip top on the cap as opposed to removing the whole cap to get a drink. This hydro flask is hand wash only. It can also be used for hot drinks too. Perfect for your workout routine or camping. Highly recommend!

I am very satisfied with the Hydro Flask. The size is very convenient for home, the gym and fits in my purse and the cupholders in my car. The opening is large enough to easily add ice Color choices are fun The cap is easy to drink from (especially for small sips) and doesn't leak. Also it is very easy to hold and still have use of your hands. The flask itself is light yet is sturdy I no longer have to buy plastic water bottles or bottled water. Here's the best part... I have found that when I add ice to the bottle they are often still there 12+ hours later. Even when I don't add ice, cold beverages stay cold (sorry, I've never tested it more than 12-14 hours - I have to sleep sometime) I will definitely purchase another one (in a larger size) for long car trips and such

Hydro Flask 21 oz Standard Mouth keeps my coffee piping hot for hours. I love the fact that I can also put cold drinks in there and they will stay ice cold. It is easy to clean and I highly recommend this product!

I live in Florida where it seems to be hot and humid most of the time so I drink a lot of water plus carry some type of water bottle wherever I go. I used to use then try to reuse the plastic water bottles but the plastic is so thin that it cracks and makes strange noises after sitting in a hot car. I was very happy to try this Hydro Flask. First of all, I love the blue color plus it is a nice size. I first used the flask in an exercise class and I enjoyed my cold water there. The strap to carry it seemed a little too small but it was okay. On another day I took the filled flask in the car with me on a long shopping day with several stops. After my last stop I was ready to drink the last of my water but the flask was very hot to touch (no shade parking spot). However once I got the top off the water inside was still cool to drink which I was very pleased to find. I haven't put a hot drink in the hydro flask yet but will definitely use it on our next long driving trip to keep our coffee warm. I really like this flask. The only thing I might want to change would be to be able to drink straight from the top rather than having to screw the top off. But that is just a minor thing.

This flask is good. I haven't tried it yet for hot things like hot chocolate when the weather gets colder. But as far as keeping the drinks cold as the day goes by, it does the job. Plus I love the blue color.

I have finally found the water bottle for my long work commute. My Hydro Flask 21 oz Standard Mouth, in Cobalt is awesome. I commute over 2 hours a day for work, and am always buying new water bottles to keep my water cold. They have all done a poor job of doing so. My water usually is lukewarm and sweats inside my work bag, which contains my laptop, so that is not ideal. This bottle passed the test, frosty cold water hours later and no sweating in my bag. It is made of stainless steel and doesn't get any dings. I have getting rid of all plastic food containers and bottles, so I love that it is BFA-free. This bottle is a must for all!

I absolutely love the color of this flask. I am so glad it has loop to hold the bottle by. It makes life so much easier. I filled this flask up with crushed ice and water at 2:00pm on monday i brought it back home left it on the counter forgot about it until the next day. At 10:30 am the next day i opened it up to put water in it and the ice was still intact and so cold! I was so amazed. IT has wonderful insulation! The only con is that sometimes its hard to unscrew the lid if its on too tight. But over all its the best thing.

I love this water bottle. Its easy to carry along and keeps my water super cold all day at work and the gym. It has a unique design and very good quality. The sweet proof finish makes hydration on the move easy.

I love my water bottle. I'm kind of a collector of metal and glass water bottles. I have...a lot. Probably too many. At 21oz, this is a little smaller than my usual choices, but it's also lighter and easier to carry around. A 40oz bottle gets heavy. These do come in bigger sizes though and I might have to treat myself to one of the 64oz. The lid is easy to open, and I love the handle. I do wish it attached the the bottle when opened, but that's not the most common feature on metal bottles. The sport lid is available to purchase separately, but it doesn't have the same handle. It keeps my water a nice temperature, but I've never actually tried it with iced water or hot beverages. I like my water just slightly colder than room temp. You don't get that overly metallic taste that a lot of cheaper metal bottles give, which I consider a huge plus. It also doesn't retain flavor, and the cap isn't rubber so it doesn't either. It's also as durable as you'd expect a stainless steel bottle to be. It's been tossed around a fair bit with out taking even a scratch. All in all, I'd say definitely worth the splurge.

I am really enjoying using my hydro flask. I have used it for both hot and cold beverages and I was surprised by how long it kept my cold drinks cold and hot drinks warm. I find it perfect to take with you on the go in the morning. The hydro flask is made of good quality materials and it is very sturdy. The top closes tight so it is leakproof which I love.

i love this product.It keeps my drinks nice and cold.It will be going everywhere with me. especially during the summer time my tea and soda will stay nice and cold in the heat.Love it and it's the perfect size.

I really enjoyed using this bottle from hydroflask because it kept my water cold for a long time. It was easy to carry and drink from. I really love that this bottle from hydro flask helps to keep your drinks hot or cold for a long time.

This hydro flask keeps my water cold for 24 hours and coffee hot for half a day.Ive this Super nice. Strong durable and easy to clean. I've dropped it and didn't dent it. Doesn't keave nasty taste after washing it unlike other brands

I love this hydro flask! I use it all the time. I did however forget it in the car overnight with my water in it, and when i went to grab it i still had ice in it and my water was still refreshingly cold! I couldn't be happier with this!
