The real deal.

  • Familiarity: I've put it through the wringer

I own many water bottles but my Hydro Flasks are always the first ones I reach for. I really like the new lid, it is more durable than the last generation. The 40 oz. size is great for long days outside.

The Only Way to Go

Hydroflask sets the bar. These bottle last forever, they come in awesome colors, and they'll keep that contents the hot or cold for days at time. If you're not rolling with Hydroflask, you're doing it wrong.

Nice water bottle

    I recieved my hydro flask today and love it. I love the color it’s pretty. This is exactly what I was looking for to use everyday . And fast shipping. Thank you.

    Great bottle!

      I ordered on a Wednesday afternoon, got to my house on Friday afternoon. Very fast shipping. Amazing bottle. I put ice water in it on Friday night at 6:00 pm and I woke up the next morning around 10:30 and it still had its ice. Perfect. The price is much cheaper on this site then

      These Bottles are Fantastic

      They come in nice colors, are totally bombproof, and keep your hot hot and your cold cold for a looong time. Almost too long honestly, but thats a good problem to have!

      Best Bottle I Own!

      • Familiarity: I've used it several times

      Awesome water bottle. Stays cold all day and the 40oz ensures you wont have to keep filling it up throughout the day.

      Simply the best

      • Familiarity: I've put it through the wringer

      I have had the same Hydro Flask for almost two years now and I take it everywhere. Keeps water extremely cold and is easy to clean while being durable. I drink significantly more water now then i ever did before.

      The only Issue I have had is I dropped it out of a car and broke the lid but hydro flask sent me a new one for free!

      Must-have item! I have several of these in different sizes and use them all of the time. Keeps my water cold and my coffee hot (I use the smaller sizes for coffee...not the 40 oz.).

      • Familiarity: I've used it several times

      I love my hydroflask. It keeps my water cold for hours. Plus, it's so light weight. Even though it's huge, it feels like you're just carrying the weight of the liquid.

      THE BEST

      • Familiarity: I've put it through the wringer

      Just like Karate Kid, these are the best around. Not only is the 40 oz big enough to keep you well hydrated for a spell, it also packs a serious punch in a dark parking lot. Ya know, just in case.


      • Familiarity: I've put it through the wringer

      I love the 40 oz because I can go longer without having to stop for water. It's not too big or heavy to carry around. I actually had my previous 40 oz Hydro Flask stolen... so I had to get a replacement.

      Household standard!

      • Familiarity: I've put it through the wringer

      Super great for keeping things warm and cold! My only complaint is that if you drop it it is easy to dent, but that doesnt seem to affect its capacity to keep things hot and cold. Great for all seasons! Lots of good colors too! I have it in orange.

      Can't Get Enough!

      • Familiarity: I've put it through the wringer

      I just can't get enough of Hydroflask bottles. I probably have one in each size and shape they make. They keep any beverage ice cold for hours and they make sure your coffee is still boiling hot 4 hours later. Seriously sometimes it is halfway through the day and I still can't drink my coffee because it seems as if I just poured it out of the pot. The 40oz bottle is a great size for all day use. I try to get myself to drink a few of these a day to keep me well hydrated.

      Cant Stop Won't Stop

        I seem to buy all things Hydroflask. I got one of these 40 ounce guys for my wife to keep her coffee warm all day and just got another for my own. Does exactly what is says and is the best quality.

        What a bottle

        • Familiarity: I've used it several times

        The bottle was a great purchase. The size was just right and it keeps my drink of choice in a good temperature.

        So Chill!

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

        Picked this one for it's great insulation, appearance, volume and portability. Keeps beverages cold for hours and the carry strap is comfortable in my hand. This won't be my last as I will be adding to my collection soon.

        My collection is getting huge

        • Familiarity: I've put it through the wringer

        I love these hydroflasks so much I continue to just acquire more and more I have one for every beverage almost. Keeps my coffee and tea hot as well as my water cold. Couldn't be more satisfied.
