    A great water bottle

    • Familiarity:I've put it through the wringer

    I bought this for my wife. She loves it. We both have multiple Hydroflask water bottles and they are great. Its nice for cocktails at a concert or just having some cold water at your desk. Reach out to me if you have any questions about Hydroflask.

    Survives the Freeze

      I bought this for my dad for Christmas because he loves taking his snow bike out early in the mornings but can't stand his frozen water bottle. Pairs nicely with a larger water bottle cage for your bike. You can't go wrong with this purchase.

      Survivor of the COLD!

      • Familiarity:I've put it through the wringer

      This hydroflask is UNBELIEVABLE.
      - I use it at both my jobs!
      -When working in the office my coffee stays burning hot for three hours. Sometimes a little too hot for my liking. It is nice though because I do not always get time to drink my coffee right away.
      -My other job is at a mountain. I stand outside for 5 hours in 20 degree weather. My hot coffee or hot coco is a lifesaver. It stays hot even in that fridged cold weather for several hours.
      -I don't use it much for cold drinks but have used it a few times for cold drinks and it stands up to its name.

      DEF one of the best bottles I own!!!

      Can't go wrong

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

      As I come from a long lineage of coffee and hot-toddy enthusiasts, the Hydroflask was a no-brainer gift. It keeps hot beverages hot to warm for what I would venture to say is about 5 hours at a time and keeps cold bevvies nice and frosty, and not to mention it fits in virtually any car's respective cupholder. This puppy doesn't leak or spill and is pretty near indestructible. I purchased my first Hydroflask about 5 years ago now and after various tumbles down cliff sides, flying off the top of my car, getting lost in the backseat for ... far too long - it's still going strong. To clean Hydroflask of the (beloved) coffee taste, I clean mine with thoroughly with warm water, a dash of Bartender's Best friend and a nice, long scrubby brush - and it's good as new!

      Some like it hot, some like it cold

      • Familiarity:I've put it through the wringer

      I've tried a couple different brands of themos-type products, and none measure up to THE flask.



      My number one favorite feature of this product is that it is 100% completely LEAKPROOF. I legitimately trust it enough to toss it in my backpack next to my dry puffy layer during a long ski tour or on top of my laptop for my ride to class. I've experienced catastrophic leakage failures with other products, by my Hydroflask has never spilled a drop.



      The second best feature is that is really does keep the hot hot, and the cold, cold. I've taken hot tea on a 3 hour long skiff ride on the Bering Sea in Alaska and arrived with a hot drink to thaw me out after the cold trip.



      The third great feature is that it is very easy to clean, so it doesn't smell forever like what you drank last. I would recommend letting it dry out with the lid off.



      Lastly, the grippy powder coating on the outside makes it durable, attractive, and prevents the hot liquid inside from burning your hands (you actually can hardly feel the heat transfer, which is why things stay so warm!). Also, flasks come in AMAZING colors.



      I would definitely recommend this size (18oz). I have other sizes and have found that the larger ones are a bit bulky and probably more fluid than one person needs for most trips. The 18oz is light enough to take anywhere, and a very nice treat in the backcountry.



      You won't be disappointed with this purchase.

      Some like it hot, some like it cold

      Perfect fit.

      A question as a gearhead we get a lot is whether the 18 ounce widemouth fits in the standard cupholder well this is to prove that it does. This is a Pontiac vibe from 2006 and with a standard size cup holder. Still a favorite size for coffee and tea and I'll always recommend a flip lid.

      Perfect fit.

      You can never ever go wrong with hydro flask products. They're the most durable, easiest to clean, and the coolest looking water bottles out there. Not to mention the insulation will rock your socks. These guys will keep hot drinks hot for up to 6 hours and cold drinks cold up to 24 hours. One of my favorite features is the sweat resistant finish for a slip free grip. The Tempshield technology guarantees no condensation or heat transfer to the outside of the bottle, making these a necessity in your life.

      Same 'ol Hyroflask

      • Familiarity:I've put it through the wringer

      there is a reason every single hydroflask item has a five star review. These things freaking rock! I have pretty much every size by now. I find the 18-24 oz sizes to be my favorite. Small enough to use as a coffee cup with the flip lid, but large enough to hold a decent amount of ice water. Pretty much you should own as many of these bad boys as I now do. Best of all is the warranty offered, no hassles ever.

      The Best Water Bottle!

        This water bottle (or any Hydro Flask, for that matter), is the bee’s knees. I have yet to find another water bottle that compares to how well this one performs. Cold water, hot coffee, this one does it all!



        The quality construction is what will first grab your attention. The powder coated color is amazing, as the bright ones pop, and the dark ones look sleek. The plastic tether between the lid and the flask itself is a must have, and after having used mine for over two months, and it shows absolutely no signs of wear. The rubber placed around the lid is a nice touch, as it makes for better grip when opening your flask to enjoy the precious liquid contents within.



        Want cold water? Throw in some ice, add your water, and there you have it! Don’t worry about leaving it in the car while you’re out and about, you’ll come back with plenty of ice to spare!

        Prefer coffee as your drink of choice (I actually have a separate Hyrdo Flask specifically for coffee and hot drinks, along with the Hydro Flip Lid)? I’d advise leaving the lid off to let it cool for a few minutes, as I made the mistake of attempting to drink from it after an hour and about burned my tongue!



        Bottom line, you won’t be disappointed with ANY Hydro Flask product! Perfect for a gift, or just for yourself. I plan to continue to add to my collection, as one can never have enough water, or water bottles for that matter.

        Awesome bottle

        • Familiarity:I've used it several times

        Ditto on what the other reviewers have said. Kept my coffee piping hot for four hours until I got back to it. Kept chilled water cold to cool for a handful of hours in an air conditioned shack. Doesn't sweat or get hot on the outside. Rough exterior dimensions: 8.5" tall, 3" diameter excluding the loop.

        Need one in every color

        • Familiarity:I've put it through the wringer

        I take this with me everywhere. I prefer the flip lip to the wide mouth, but it's nice to have both options. I leave in the morning with ice water which remains cold through my morning classes and through work in the afternoon. I take it everywhere, and it's made drinking more water much easier since the liquid always is cold (nobody likes stale warm water).

        Are any of the colors aside from stainless steel smooth on the outside? I have a SS and an orange and I can't use the orange one in the bottle sleeve of my jackets because the rough exterior will shred the pocket.

        Hi Eddie,

        Thanks for the question. The colored versions all use the same powder coating to make for a very durable and long lasting color. Unfortunately this means that they are all going to cause the same issue when placed in your pocket.
