    • Familiarity: I've put it through the wringer

    I carry this thing everywhere, Add the straw top, you will drink more. A LOT MORE. I throw it in the jeep. Down the stairs. At my neighbors cat. Down my gullet. Can't hurt it. Can only give it...Character... :)

    Hydration is key

    • Familiarity: I've put it through the wringer

    Keeps your drink super hot or super cold. 40oz is just the perfect amount so you don't have to keep getting up and down to fill the water bottle. Get chu one.

    Impressive as heck

    • Familiarity: I've used it several times

    I purchased this Hydroflask for my day long outdoor outings in the hope that it would keep my water ice cold in the scorching weather. And boy, did it deliver!

    I filled up my Hydroflask in the early morning with half cold water, half ice. By mid afternoon I had drank all of the water and the ice stayed, well, ice. I had to leave the top off in hopes that the ice would melt so I could drink it. Unfortunately even with the top off, the ice was reluctant to melt. My day at the lake ended and I went home with some ice still in the Hydroflask and forgot about it till the next day. I opened it up and... the ice was still there! Whaaaaat

    Stay Hydrated

    Use this every day. Holds SO much water, I love it. Keeps cold for hours on end. I will never be thirsty again. Also, plenty of room for stickers if you need somewhere to put those. Be sure to pick up the Hydro Flask Wide Mouth Straw Lid too and take your hydration to the next level.

    Hydro Flask for the win!

    Already love this bottle, just needed it in my favorite color Olive. I am about to Order a Navy Blue one as well. Can never have enough bottles. DRINK WATER!

    Everyday Bottle!

      bought a couple of these for my parents who live in the hot state of arizona where they needed something to keep their water cold all day - and this does the job! perfect size and function.

      Favorite bottle

      • Familiarity: I've put it through the wringer

      Everyone who owns one will agree that these are the best bottles around for keeping any liquid hot or cold for super long periods of time. The seal is also consistently tight and keeps carbonated beverages fresh. If you drop things a lot (like me) these will get small dents pretty easily, but even with the dents it's still my favorite bottle.

      Hot or Cold drinks anywhere anytime

      • Familiarity: I've put it through the wringer

      I used to exclusively use a Nalgene to carry my water. In the winters the water was frozen and in the summer my water was boiling hot. No more! The Hydroflask has changed my life. Keeps my ice water icey all day, even in 100 degree Utah summers. Keeps beer cold so you can have a refreshing reward after the long ride. Also keeps coffee very very hot if you are a caffeine addict like me and need over a liter of coffee to function.

      A MUST HAVE!

      • Familiarity: I've used it several times

      I love my hydro flask, I always have it with me! Fill it full with ice and water and you will have ice cold water all day! You can never have enough hydro flasks!

      graduating from 18 oz to 40 oz

      • Familiarity: I've used it several times

      i have a blueish 18oz that i keep at work and take w/me when i go out for lunch, as I work in dc. who wants to spend an easy $2.50 per drink when water at work with ice is free and ice cold? i've gotten used to bringing the 18oz w me whever I go. but now that it's summerish time here in dc, that means more hydration...and nothings better than 40oz of iiice cold water.

      i have another hydroflask that i take w/me when i travel and it's a lifesaver...add ice to the brim, and slowly during the day it melts but not completely....

      i wonder why others don't get a hydroflask to keep hydrated?!

      Love Hydro Flask - but dents do occur

      • Familiarity: I've put it through the wringer

      I love Hydro Flak - the colors and the functionality make me want to buy more (for myself, family and friends)! I got the 40 oz wide mouth in the outgoing color of Mango on sale from Backcountry. Love the size, that it's big enough to hold all the water I need during the day. The only thing was that it came wrapped in a bubble sheet (not a sealed bag), which I didn't know until I dropped on the hard concrete floor twice (I took it out of the wrap to see it in the garage, then put it back in the wrap, without realizing it was just a bubble sheet wrapped around the body of the bottle - open both the top and bottom - and not a bubble bag with only one side open! Sadly the bottom of the bottom got dents before I even got to use it. :( The good news is that nothing cracked or deformed badly (so it's a sturdy product!). I'm keeping it because I figured I'd get dents sooner or later as I use it on a daily basis. So just be careful handling it, people!


        I loved the color! It worked perfect throughout the school day for my daughter, and she would come home with ice cold water. it was really fast shopping, until it got stolen at my daughters school. we bought a flamingo 40 oz so she can still have one. worth the high price!
