Cant Stop Won't Stop

    I seem to buy all things Hydroflask. I got one of these 40 ounce guys for my wife to keep her coffee warm all day and just got another for my own. Does exactly what is says and is the best quality.

    What a bottle

    • Familiarity: I've used it several times

    The bottle was a great purchase. The size was just right and it keeps my drink of choice in a good temperature.

    So Chill!

    • Familiarity: I've used it once or twice and have initial impressions

    Picked this one for it's great insulation, appearance, volume and portability. Keeps beverages cold for hours and the carry strap is comfortable in my hand. This won't be my last as I will be adding to my collection soon.

    My collection is getting huge

    • Familiarity: I've put it through the wringer

    I love these hydroflasks so much I continue to just acquire more and more I have one for every beverage almost. Keeps my coffee and tea hot as well as my water cold. Couldn't be more satisfied.

    Only beverage container worth using!

    • Familiarity: I've put it through the wringer

    I think I have an obsession. I own the 32oz, 18oz, and 12oz wide mouth bottles, and had to go back for the 40oz to add to my collection! I only use the 40oz for water, but like all the other Hydro Flasks it is durable, quality, and keeps my drinks cold/hot for longer than any other bottle I've ever owned. These make awesome gifts due to the adorable color ways, and I love that you can purchase different lids to go with them. Winner!

    Stays cold forever

    • Familiarity: I've used it several times

    The wife loves this prize. She can keep something warm or cold for hours if not days. Great product.

    Great beverage container

      I use this all the time and really do like it. I was stoked to find out that the flip lids fit as well. Now I use it all the time.


        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!!!!

        If you have any questions about this bladder or any other gear shoot me an email at or give me a call at 801-523-4053

        • 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!

          Still Awesome

          • Familiarity: I've put it through the wringer

          I just keep buying more. Great gifts!

          Hydroflask is always the right call!

          • Familiarity: I've put it through the wringer

          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.

          Best water bottle

            My favorite! Put ice water in it and there was still ice in there 24 hours later. Awesome


            • Familiarity: I've put it through the wringer

            I really like having a larger water bottle. 40 oz is great when you need it and keeps the temp.

            Keeps water cold all day

              I love that I can be in the sun all day and still be able to have cold water. The perfect size for hiking.
