    ICE FOR DAYS

      I have several for different occasions. This one tends to keep ice even longer because you don't open it up and let a bunch of hot air in every time you get a drink. I have filled this with ice water, left it in my car in the burning sun all day and not melted the ice. This thing is amazing!!!!

      • Familiarity: I've put it through the wringer

      From ice cold water all day long in 100+ degree heat to frosty cocktails at night, there isn't another water bottle I would trust to keep my drinks cold as long as this Hydroflask does. Love everything from the mouthpiece to the clippable handle.

      Handle carry is great

      • Familiarity: I've put it through the wringer

      I carry this with me wherever I go. The handle makes carrying it very convenient when my hands are full of everything else in my life.

      Best bottle on the market

      • Familiarity: I've put it through the wringer

      Hydro Flask makes the most solid water bottle in the game. Keeps stuff hot or cold for hours. Time to upgrade from that single wall water bottle that doesn't keep your drinks hot or cold and invest in the most solid bottle. You won't regret it!

      Big Boy

        Hydro flask just exudes quality. Their products are dynamite and their water bottles are, time in and time out, the best on the market. If you are looking for a bottle to carry to work, or school, or even on extended hikes the hydro flask is a great option.

        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
