    So far, real good

    • Familiarity: I've put it through the wringer

    I've had the Hydro Flask 21oz water bottle for a month now and love it. It keeps drinks hot or cold for hours, closes tightly and has a convenient handle on the top. Highly recommended.

    Keeps Bevs Cold for days

    • Familiarity: I've put it through the wringer

    If not in direct sunlight, ice lasts in this bottle for over a day sometimes, and even when the ice melts, it stays cold for a long time afterwards. Easy to pack and very durable. It seals nicely as well.

    Drink Water Feel Good

    • Familiarity: I've put it through the wringer

    This water bottle is awesome. It always amazes me when I leave ice in the bottle and wake up the next morning to still find ice in my water! Couldn't ask for any more, hydro flask does not disappoint

    Needed the new colors

    • Familiarity: I've put it through the wringer

    These Hydro Flasks have a lifetime warranty. If your water is not cold/hot like it used to you can send them to Hydro Flask!! That is a huge perk. But, sometimes you just want the new color, so here I am buying the new color. The new lid is a huge upgrade. I don't feel like my finger will break off when I carry it around.

    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.

      Top Bottle

        Hydroflask knows whats up- they make a great bottle, and they actually WORK to keep your beverages hot or cold! Super easy to clean too, so you can put a variety of drinks in it and the bottle won't cling on to the taste. Very durable, easy to swap out the caps- what's not to love!

        Switched out my workout bottle

        • Familiarity: I've put it through the wringer

        Keeps water tasting good and cold for hours. I switched out my insulated plastic bottle I usually use when teaching spin classes for this one. Love Hydroflask.
