    My go to gift

    • Familiarity: I've put it through the wringer

    I'm a school teacher and every teacher has water bottle envy... So I get these for gifts for all the colleagues. They absolutely love them and for good reason: all day ice even after a few fill ups!

    I take this with me everywhere

    • Familiarity: I've put it through the wringer

    Some people think 40oz is too big for everyday use but I love it. I carry this to every meeting and event I go to. I love it because I don't have to fill up all the time. It keeps water cold and work just as advertised.

    Extraordinary!!

      A must have if you drink a lot of liquids trough the day, holds temperature for a very long time. Took it to the beach with cold beer under a temperature of over 95F and it stayed super cold! Great choice.

      DOES THE JOB WELL

      • Familiarity: I've put it through the wringer

      Keep your cold super cold.. thats all there is to it! One downfall is the size of the top makes drinking when moving pretty tough. Its just big enough to run in to the bridge of my nose.. wish it was a bit bigger or maybe a bit smaller!

      Keep it cold

      • Familiarity: I've put it through the wringer

      This thing will literally keep your water cold for 2 days in 100 degree heat. It's rumored that the designers of this bottle have created an artificial polar atmosphere on the interior of this bottle. Scientists are working to apply this same technology to our polar ice caps. Fascinating Stuff!
      All jokes aside, this is a killer bottle to keep your beverage of choice chilled (or hot!).

      Must have!

      • Familiarity: I've put it through the wringer

      These are the best! Keeping your water cold for hours on hours. It really make drinking water more enjoyable because you always have ice cold, refreshing water. The vacuum design is great, it insulates very well. You can leave this in the sun all day and your water will still stay ice cold! I'd recommend this to everyone. Really everyone, we need water to survive, and when you're 4 hours into a grueling hike all you want is an ice cold refreshing drink. You'll have it with this water bottle. I opted to go with the 40 oz so that I don't have to refill it all the time. I can't get enough of these Hydroflasks!

      My go to bottle

      • Familiarity: I've put it through the wringer

      I've bought 3-4 of these, all of which are awesome. If you're on the fence between the 32 and 40 I would highly suggest sizing up as the 40oz is not much larger than the 32oz.

      ICE is NICE!

      • Familiarity: I've used it several times

      Great water bottle! Perfect size to keep you hydrated for hours, works great to keep water cold throughout the day. I couldn't believe I still had a bottle full of ice after a long day in the desert. Doesn't seem to be any way this thing could leak unless you didn't tighten the cap. Highly recommended!

      Keeps ice cold for over a day

      • Familiarity: I've put it through the wringer

      These are great to have. You put a warm drink in with ice, seal the lid, and the beverage is cooled down within 10 minutes. I haven't tried any warm liquids yet, but I'm assuming the same effect would happen. Great to have. Highly recommend.

      Water is better COLD

      • Familiarity: I've put it through the wringer

      My hydro flask rarely leaves my side. I wake up in the morning, throw a bunch of ice and water in and by the time 5 PM rolls around, my water is still ice cold and my ice cubes are still in tact. Don't drink from plastic water bottles out in the sun! First of all, hot water is not ideal to quench thirst and secondly, that boiling hot plastic is releasing chemicals into your water. The weight is a bit much if your cutting ounces on your back packing rig, but the function outweighs all in my opinion. Keep your coffe hot on the mountain and keep your water cold in the desert!

      In love

      • Familiarity: I've put it through the wringer

      This bottle will keep ice for over 24 hours! My girlfriend and I have 6 hydroflask products combined and we cannot get enough. The larger bottle size is perfect if you're sharing or you want to stay hydrated all day while keeping your drink iced then look no further.
