    This thing ROCKS!

    • Familiarity: I've put it through the wringer

    I have had my Hydro Flask for just over two years and I love it. In the winter I bring it skiing with hot tea, coco, or soup and in the summer I keep it full of ice water and it stays cool all day. As long as you don's dent it, it will work forever!

    Hydroflask is always the right call!

    I had a lot of options to choose from when picking a water bottle to take up to Strugis this year for Bike Week. During the rally, ice becomes like gold. Being able to keep ice frozen all day is vital to my success as a vendor. I had narrowed down the options between this and the YETI. I knew from experience with Hydroflask that it would perform just as well and I jumped on this in Sage, my favorite color. I had a blast and the 40 OZ bottle from Hydroflask kept my body extremely well hydrated all rally long. Tell all your friends and family! Vacuum insulation would keep my ice frozen over night even.

    Keeps Everything Cool

    • Familiarity: I've put it through the wringer

    I use this mostly for casual every day use as something to bring my milk to work in. It works great! I can get to work and maintain a fresh bowl of cold cereal any day of the week. I've used it backpacking on a summer day and it has held ice for over 24 hours. Love it! Would recommend for anyone that has had the same milk issue that I no longer have!!!

    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.
