Iced water all day!

  • Familiarity: I've put it through the wringer

I have had my 40oz hydro flask for 5 years now and it has been more reliable than my tacoma. It will keep you hydrated and cool all year long. Mine has slowly started to get some dents so it might be time for a replacement but I would buy this product 5 times over.

Love my hydro flask

    I loveee it. It’s big enough to last me a few hours and keeps my drink nice and cold.

    Hydro Flask 40oz Wide Mouth Water Bottle

      Only complaint is it has some weight too it.
      if you care if your water is cold or hot for long periods this is for you.

      It's amazing!

        Every time I show someone how it still has ice the day after I fill it they are as amazed as I am!! I am definitely giving these as gifts :)

        Cold water all day long!!!

        • Familiarity: I've put it through the wringer

        I absolutely love this water bottle because I enjoy having cold water at all times. This water bottle is by far the most insulated water bottle on the market. It also works just as well for hot drinks. Perfect for winter time to have in your pack because you don't have to worry about your water freezing. The 40 oz size is perfect for having a drink that will last all day but it's also not too bulky. I highly recommend everyone to own a hydro flask.

        Cold water all day long!!!

        Cool and warm 24/7 everywhere you go

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

        Really durable and keep your liquid at the temperature at the way you want it for a while!

        Awesome

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

        This product is awesome, brought this for my brother and he loves it. I like the color of it

        Amazing Bottle

        • Familiarity: I've put it through the wringer

        I used every single day and keeps water cold as expected. I recommend it.

        Hydration is key

        • Familiarity: I've put it through the wringer

        Keeps your drink super hot or super cold. 40oz is just the perfect amount so you don't have to keep getting up and down to fill the water bottle. Get chu one.

        Bottle review

          Cool looking bottle , the straw lid sucks, this bottle has more hype then it should have. There are way better bottles out there like camel bam or yeti.

          40oz is a must!

          • Familiarity: I've put it through the wringer

          Ive had other sizes of hydroflasks and i feel like I'm refilling them way too often. With the 40oz bottle it lasts way longer!

          PEOPLE WILL DRINK AGAIN!

          • Familiarity: I've put it through the wringer

          I carry this thing everywhere, Add the straw top, you will drink more. A LOT MORE. I throw it in the jeep. Down the stairs. At my neighbors cat. Down my gullet. Can't hurt it. Can only give it...Character... :)

          Impressive as heck

          • Familiarity: I've used it several times

          I purchased this Hydroflask for my day long outdoor outings in the hope that it would keep my water ice cold in the scorching weather. And boy, did it deliver!

          I filled up my Hydroflask in the early morning with half cold water, half ice. By mid afternoon I had drank all of the water and the ice stayed, well, ice. I had to leave the top off in hopes that the ice would melt so I could drink it. Unfortunately even with the top off, the ice was reluctant to melt. My day at the lake ended and I went home with some ice still in the Hydroflask and forgot about it till the next day. I opened it up and... the ice was still there! Whaaaaat

          Stay Hydrated

          • Familiarity: I've put it through the wringer

          Use this every day. Holds SO much water, I love it. Keeps cold for hours on end. I will never be thirsty again. Also, plenty of room for stickers if you need somewhere to put those. Be sure to pick up the Hydro Flask Wide Mouth Straw Lid too and take your hydration to the next level.

          Ice lasted for days

            Very cool bottle, ice would last for couple of days, must have for utah summer.

            Hydro Flask for the win!

            • Familiarity: I've used it several times

            Already love this bottle, just needed it in my favorite color Olive. I am about to Order a Navy Blue one as well. Can never have enough bottles. DRINK WATER!

            Everyday Bottle!

              bought a couple of these for my parents who live in the hot state of arizona where they needed something to keep their water cold all day - and this does the job! perfect size and function.

              YAY

              • Familiarity: I've put it through the wringer

              I love the 40 oz. I've usually only had about 32 oz or so, but the extra 8 oz really is nice!
