    There's nothing standard about it.

    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.

    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.

    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.

      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.

      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.

      Killer

      • Familiarity: I've put it through the wringer

      Perfect HF for the gym or hiking or any other outdoor activity. Some of the larger sizes can be a bit heavy and cumbersome but this guy is perfect! Love the ease of the sport lid also.

      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!!!!

        Nothing But Love

        • Familiarity: I've put it through the wringer

        Nothing but love for this thing! Everyone needs to own a hydro flask, they are seriously the best! Whether your drink is hot or cold, this thing will keep it insulated all day long.

        Unanswered Question

        Does this item have a standard cap AND a sports cap? Or just the sports cap? TIA!
