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.).

Hydro Flask 40 oz Wid Mouth Water Bottle

  • 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.


  • 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.

    Only beverage container worth using!

    • Familiarity: I've put it through the wringer

    I think I have an obsession. I own the 32oz, 18oz, and 12oz wide mouth bottles, and had to go back for the 40oz to add to my collection! I only use the 40oz for water, but like all the other Hydro Flasks it is durable, quality, and keeps my drinks cold/hot for longer than any other bottle I've ever owned. These make awesome gifts due to the adorable color ways, and I love that you can purchase different lids to go with them. Winner!

    If you have any further questions about this product I am happy to help! You can call me directly at 801-619-7488, or email me at

    Stays cold forever

    • Familiarity: I've used it several times

    The wife loves this prize. She can keep something warm or cold for hours if not days. Great product.

    Great beverage container

      I use this all the time and really do like it. I was stoked to find out that the flip lids fit as well. Now I use it all the time.


        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!!!!

        If you have any questions about this bladder or any other gear shoot me an email at or give me a call at 801-523-4053

        From ice cold water all day long in 100+ degree heat to frosty cocktails at night, there isn't another water bottle I would trust to keep my drinks cold as long as this Hydroflask does. Love everything from the mouthpiece to the clippable handle.

        Handle carry is great

        • Familiarity: I've put it through the wringer

        I carry this with me wherever I go. The handle makes carrying it very convenient when my hands are full of everything else in my life.
