    21oz Standard Sport Cap Water Bottle

    A plastic water bottle is standard. Hydro Flask's Standard Water Bottle with Sport Cap's stainless steel construction is anything but standard. Grouped with TempShield insulation, the Standard Water Bottle assures a pure drinking experience whether you're drinking something hot for eight hours, or something cold for a full day. Hydro Flask coated this bottle in grippy, sweat-free powder, and the sport cap is ideal for running or hiking.

    • There's nothing standard about this water bottle
    • Stainless steel construction for a pure taste
    • TempShield insulation keeps drinks cold for a full day
    • Durable, sweat-free powder coating for a solid grip
    • Sport cap for performance-oriented activities

    Love my Hydro Flask

    • Familiarity: I've put it through the wringer

    I love my Hydro Flask, it is the perfect size in every way. 20 ounces is just the perfect amount to quench my thirst and not be too much to carry around. The ring on the lid is perfect for carrying it with me. I absolutely love that it fits in the cup holder in my car, it is my favorite thing about this Hydro Flask. I love my new Hydro Flask and take it with me everywhere.

    👍👍👍

    Cold, Cold, Cold, Fantastic

    • Familiarity: I've used it several times

    My daughter uses this for school and long car rides. Loves that his drink stays cold with only a little bit of ice added in. Take it everywhere.

    Cold Water all day---CHECK!

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

    My daughter loves this hydroflask! The color, the spout, the way it keeps it cold!! It's worth the investment!

    Nice deal

    • Familiarity: I've put it through the wringer

    Love this option to get the sport lid and bottle at the same time.

    LOVE IT

      SUPER NICE

      Bottle is great, sports cap leaks

        We've had these bottles for a few years and they are as good as most aluminum water bottles. The problem is the Sports cap. We purchased the sports caps ( 3 of them ) to replace the original Flex Caps and they work for a little while then develop a leak/ drip. Back country graciously replaced one of them. Ive reached out to Hydro Flask with no results. In fact if you look at the Hydro Flask web site , the Sports cap description has been updated to state it "is not leak proof"

        It is great as a one handed open/close with your teeth cap, but if it falls over in your car/ bag. it will leak.

        Bottle is great, sports cap leaks

        Appreciate the thorough review and that you have pointed this out for other customers!

        Water stays cold all day

        • Familiarity: I've put it through the wringer

        Really does keep your water cool all day! I love this size as well

        Great gift

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

        Bought this as a gift for one of my friends who enjoy going to the gym! The lid makes it easy to drink out of which is great and they loved it! It’s nice and slim which makes it easy to carry around!

        Worth Every Penny!

        • Familiarity: I've put it through the wringer

        For me it was very hard to buy my first hydo flask, because of the cost. This water bottle doesn't compare to any other water bottles out there! Keeps my drinks either hot or cold. I also find myself drinking more water because it keeps it so cold. So my body is health and happy. I now own 5...

        Always a good gift

        • Familiarity: I've put it through the wringer

        Hydro Flasks make great gifts because everyone loves and always needs a nice water bottle but doesn't necessarily always want to buy one themselves. When I am at a loss for ideas, or a friend/family member keeps commenting on my bottle, I always go Hydro Flask!

        Great Bottle

        • Familiarity: I've put it through the wringer

        Works as advertised, I've owned a lot of hydro flask containers and bottles and they all work really well. Just always be aware that the estimates of how long ice and heat can remain in a vessel is based on a lot of factors. However, I love these and continue to go back to hydro flask for the colors and the style.

        Bottle is great and keeps drink cold

        • Familiarity: I've used it several times

        Keeps liquids nice and cold but the sport cap is junk. It seperated into 2 pieces leaving the threaded piece still in the bottle. Now I have to buy a new cap I guess, I am reluctant since the cap was only in use for 2 months.

        Back for More

        • Familiarity: I've put it through the wringer

        Another Hydroflask... Keep coming back for more because they genuinely keep my water cold and don't sweat. Love the olive color.

        The Perfect Water Bottle

        • Familiarity: I've used it several times

        This water bottle is great for work or the gym. It can be used anywhere and keeps the water cold no matter the temperature. I left it in the car on a sunny day and it still stayed cold.

        Life is better with Hydroflask

        • Familiarity: I've put it through the wringer

        I love all things Hydroflask, but this little bottle is a perfect size and a cooler color. I bought the kiwi as a gift since I use my big daddy flask all day every day, and now I think I have a friend for life in the recipient. Hydroflasks maintain temperature, are durable like your ol' Uncle Charlie who just won't die, and are easy to clean. Big love.

        Perfect for the gym

        • Familiarity: I've put it through the wringer

        I love this hydroflask for the gym or short hiking trips. Keeps my water super cold and the ice in it will last for hours. Super convenient that you don't have to take off the lid overtime you need a drink.

        Kid sized

        • Familiarity: I've used it several times

        Always loved the larger 32Oz so we decided to get some of the smaller ones for niece and nephews. Can't go wrong with these.
