    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!!!!

      Ice Cold Beverages!

      • Familiarity: I've put it through the wringer

      What is there to say about Hydro Flask that people don't already know?! It keeps beverages cold for hours, the look of the bottle is trendy and it's basically indestructible.

      I'll take this bottle on a hike and leave it in the car to come out to an ice cold drink with the ice still in there! You can literally never gone wrong with any of Hydro Flask products!

      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

      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.

        Perfect for car travel

        • Familiarity: I've put it through the wringer

        Fits in cup holders great so you don't have to worry about it on the drive to work. I purchased the flip lid to go with it to make drinking coffee on the go easy and mess free.

        Hot Hot and Cold Cold

        • Familiarity: I've put it through the wringer

        This water bottle is sweet! looks good, and keeps hot drinks hot and cold drinks cold WAY longer than any other bottle I have ever used. Worth the investment!

        Hydro Flask is the BEST!

        • Familiarity: I've used it several times

        I love my Hydro Flasks! They are amazing at keeping my drinks cold for long periods of time even in hot temperatures! The reason that I did a 4 star review on this was because the color I ordered (Graphite) has began to show streaks on it. I am not sure where the streaks are coming from but I have not had this happen with any of the other colors I have ordered. It is not affecting the function of the product and I still love my Hydro Flask!

        Cup Holder Compatible!

        • Familiarity: I've put it through the wringer

        By now I think just about everybody knows what a killer brand Hydroflask is, so I won't rave about it. What is amazing about this particular bottle is the 18oz size, I love how it fits in my hands, it's not super heavy like the 32oz, and it fits in my car cup holder which was the real selling point for me. I've purchased quite a few of these since they make the PERFECT gifts.

        Hydroflasks are the Best!

        • Familiarity: I've put it through the wringer

        I gave several Hydroflasks as gifts this past holiday season and everyone LOVED them. They keep the hot stuff hot and the cold stuff cold, with no leaking or sweating on the outside. You can't go wrong if you buy one.

        Great Product!

        • Familiarity: I've used it several times

        I have always heard a great deal of hype about the Hydoflasks. The rage is real! I used this to put hot chocolate in while boarding, ended up leaving in the car while I was on the slopes. When I came back to the car about 7 hours later my hot chocolate was almost as hot as when I first put it in the bottle. Definetly a fan. Ended up buying a bunch more for some christmas gifts to my friends.
