Hydro Flask Water Bottle - Stainless Steel & Vacuum Insulated - Wide Mouth with Leak Proof Flex Cap - 18 oz, Black

I absolutely love it. My biggest problem with other water bottles was that it would never stay cold. After an hour or so, the cold water would quickly turn to lukewarm water. Also, i'm a bit on the clumsy side so i would drop my water bottles frequently too. My water bottles would always end up dented or even worse.. shattered/broken. Sometimes the top cap would break and i wouldn't be able to close it anymore. This product solves all of those issues. I've kept water in it overnight and it's still cold! It's not as cold as it first was, but it's definitely not lukewarm either. (I learned that it will stay cold even longer if you put in ice with your water. May seem a little obvious, but it makes a huge difference!) I've also dropped it a few times, but not even a scratch so far. My only dislike about this bottle is the cap. It's a bit tiresome having to turn it open every single time, but i figure the cap is designed this way to help with the insulation. I've ordered a couple other lids (flip cup and straw) so hopefully that will solve my issue. Overall, i am in love with this water bottle! You can't go wrong with it!

I bought two of these at a specialty sporting goods store for a trip to Iceland. Dehydration is always a concern of mine and I wanted a bottle that was really good. My husband and I LOVE them. No leak or sweating - laid on it's side in our backpack. Hot stayed hot for hours - my husband now uses his every morning to go to work. Cold stays cold for hours - I made an iced tea the other day and left it in my 85 degree car for 2 hours and it was still ice cold. I went back to the shop to get two for my adult children since they are traveling soon as well. Store was all out so I went on Amazon - next time I will do that first. Color selection was great too. I highly recommend this product - pure performance and quality.

I received this hydro flask from my son as a Christmas present. He was VERY annoyed that I use plastic water bottles, even though I reuse them. So he ordered this insulated flask for me, knowing it would not only keep water cool, but that it would also keep coffee or tea warm. It's not like I was unfamiliar with thermal liquid containers, but none of them have been any different than that which came before. So I was like, 'Okay, that's nice, keep stuff warm or cold, yeah yeah yeah, thank you, sweetie.'Well . . . obviously I had no idea.When I realized that my morning coffee was still 'burn my lips hot' by 4 p.m., we decided to test it. We poured hot tea in to the thermos one morning, then screwed on the lid. We opened it and stuck in our fingers each evening and morning to test the temperature. The result? Three days. It kept tea hot for THREE FREAKING DAYS. This thing is unbelievable and I love it!!!You deserve this. Get one!

And skateboarding, airplane trips, surfing, marching band practice, camping, hiking, orchestra and where ever else my teenage son takes it. The first extremely well-traveled Hydro Flask was stolen (maybe it was the multiple layers of skateboarding stickers?) much to his dismay. But I think it was money well spent and didn't hesitate to buy an identical replacement. He likes to fill it with half water and half ice for cold water all day long. 18oz seems to be the perfect size to fit in the water bottle pouch on the outside of most backpacks. Or he can carabiner the loop on the top to his trumpet case strap. Maybe I'll buy yet one more just in case...

I love my hydroflask! I use it everyday and it keeps my water cold and my coffee warm which is a plus considering how I use multiple containers before that didn't work as well. It does dent pretty easily on the top but other than that it's pretty durable! A bit pricey but definitely worth the investment.

Received mine with a scratch on it and got a full refund. Very happy with this purchase. Didn't think I needed an insulated bottle but decided to give this a try since everyone is so crazy about hydroflasks these days. I must admit it is wonderful for my water not to go warm after leaving it in my backpack for a couple hours and to always know that every time I pull out my hydro flask during class, a wonderfully cool and refreshing sip of water awaits me. Have been complimented many times for the looks of this sleek hydroflask as well! Water stays cold in it for a very long time. Have never tested the length of coldness but I have never found it to disappoint.

I don't want to drink out of regular glasses anymore. I seriously use a hydroflask every waking moment of my life.Too often I'd find that my drinks/ice cubes would melt and become stagnant.. This is a godsend of a product. I could fill up my hydroflask right before I go to bed, and when I wake up.. it's still just as cold as the moment the cubes came out of the freezer, and the water came out of the fridge.Bought 2 more, and now I've got my family hooked too. People see me carrying this everywhere and they ask "what's in there?" like it's some type of secret recipe.. Nope it's just water, ICE COLD WATER.Haven't tried it for hot beverages but I've heard that it works just as great. Don't sleep on this!

Keeps your drink cold for a LONG time. I have not tested it with hot beverages yet, but I'm sure it works fine. The lip of the bottle is comfortable to drink from, but if you are not careful you can spill it easily. The coating of the bottle has a nice touch, but it may be slippery if you have dry hands. But overall great bottle, best one I have ever had!
