    Perfect Size

    • Familiarity: I've put it through the wringer

    The 40 oz has become my favorite size because it holds enough water to last you for a while. Won't fit in most cup holders but isnt a pain to carry and your water can stay whatever temperature you like for a long long time

    Kid tested water approved

      I love my hydro flask its my favorite vessel for h20. It is also my 1-year-old son’s favorite tool for banging on the kitchen floor at 6am. As its metallic ring pierces through the sleeping household, I’m reminded how much I Love. My. Hydro Flask.

      Twice as Nice

      • Familiarity: I gave it as a gift but have feedback to share

      I love my hydroflask so much that I bought one for my husband who regularly drinks beer on hot days without hydrating. If he does this on his day off, I get home from work and he's tired and cranky - full on no go for the wife. It's no small thing to say that this 40 ouncer may have saved our marriage. He drinks, then he drinks, and he feels great and happy - all because the hydroflask is large capacity, temperature controlled, and easy to sip from (if you get the sippy straw). I think we're going to make it.

      Everybody's Gettin one

      • Familiarity: I've put it through the wringer

      There is a reason it seems like every other person you see is holding a hydroflask.... They are amazing. Keeps your beverages hot for hours or cold for days literally. Ice will stay in these for days. Get one.

      Drown your thirst!

        With the quality of a normal Hydro Flask ( amazing) and a wider than normal mouth, you can be sure to know: When you're thirsty, pour that waterfall of boiling hot coffee out at will!

        OR prepare to quench your thirst with freezing cold water after a long hike.

        Whatever floats your boat, this thing will do!

        My favorite water bottle.

        • Familiarity: I've put it through the wringer

        I have a few of these they do exactly what they are supposed to keep stuff thats cold cold and stuff that is hot hot, I got myself the sage color and its a perfect forest green I absolutely love it. I bought my girlfriend the mint color one as well and she loves the color and bottle as much as I do.

        Love This Thing!

        • Familiarity: I've put it through the wringer

        These bottles are great for just about anything. They're durable and will keep whatever you put in them cold or hot for a long time. I have two for myself and they're my go-to item if I need to buy a gift for someone and run out of ideas.

        Amazing Water Bottle

        • Familiarity: I've used it several times

        This is such a great bottle. It's heavy duty, keeps my beverages cool for HOURSSSSSS (apparently it will keep it hot too, but I haven't tried anything but water in it yet), and it's a great size to keep up with hydrating yourself. 2-3 of these a day is key!
