  • 18 oz Wide Mouth is rated 3.8 out of 5 by 29.
    Rated 5 out of 5 by from Great for traveling! Love this bottle! It is easier to hold while driving and fits perfect into cup holders in the car. Also great for work. Bought the flip top cap, which is convenient and easier to drive out of at work and in the car. Just ordered my second bottle in a different color so I can leave one at work!

    Rated 5 out of 5 by from Love it! Perfect and worth every penny. Keeps my water cold (haven’t tried anything hot but I’m sure it works). Love how it looks too!

    Rated 5 out of 5 by from I am obsessed! I bought the red one a few months ago, it has been amazing! keeps my water cold for hours and my coffee/tea hot for hours. I have since this purchase bought the bigger bottle and the top for drinking coffee on the go. I am growing my hydroflask collection and I am obsessed with everything I’ve bought! SO WORTH IT!

    Rated 5 out of 5 by from Keeps stuff Hot for a long time About a month ago I bought a hydro flask and it has done a great job at keeping my water cold while in direct sunlight for extended periods of time, and kept my piping hot tea hot from 9 a.m to 1 p.m.

    Rated 5 out of 5 by from Cold water is the best accessory Hydroflask has changed my hydration game. I've had my Hydroflask for about a year and have purchased several more for family and friends as gifts. I carry mine with me everywhere, through daily office meetings, gym workouts, frequent travel, or even just on my nightstand. It's very much engrained with my day to day life tasks. The 18 oz is the perfect size; it fits easily in a cup holder, on the side pouch of my backpack, and doesn't get too heavy once it is filled up with deliciously cold water. I just recently lost my Hydroflask and am back on the site purchasing a new one.

    Rated 5 out of 5 by from Amazing product! It is the perfect size for me to sip on all day at work. I use mine for coffee and it keeps it warm over an 8 hour day. It's also great to have some warm coffee waiting in the car after a winter hike! I have dropped mine a few times and it takes a good impact for a dent to be made. They are easy to clean and have not retained a smell after daily use for a few months.

    Rated 5 out of 5 by from Great bottle for daily use. I bought the black 18oz with the Flex Cap, and I also bought a Hyrdo Flip Lid as well. I use the Hydro Flip Lid daily while drinking at my desk or in the car. The bottle fits easily in my cup holders, and the flip lid is easy to open and drink from in the car or on the go. I use the flex cap to seal the bottle up when I'm tossing it in my backpack or gym bag. And even thought the flip lid is billed as "not leak proof", it still does an awesome job at not leaking or dripping everywhere. I would totally buy this again and recommend buying both the Flex Cap and Hydro Flip Lid.

    Rated 5 out of 5 by from It does everything a flask does and better My daughter buys flasks (she has shelves full of them) to try and find one which works good. After buying yours she has stopped she states this is the one she has been looking for. BUT now she keeps buying yours. One for her mom one for me and another big one for her. And now a 5gall water dispenser to keep them filled. During the day, because of her job, it's left in her vehicle all day, temp of over 100f and it's still very cold and the ice insid has not melted. Thanks for a great product.

    Rated 5 out of 5 by from The Best Waterbottle Out There! I bought my 18oz wide mouth nearly a year ago and it's been great. I'm in the Air Force so when I deployed to Afghanistan, I took it with me. It can get up to 125 degrees Fahrenheit there and this bottle kept my water cold all day. I had to keep it close by at all times because the other troops were always eyeing it! I use the straw lid for it which is great as well but if it isn't pushed all the way down, it can leak which makes sense that it would happen. Easy fix is just to ensure it's pushed down. I'm going to be looking at purchasing a larger size one soon and I know it'll hold up just like this one has!

    Rated 5 out of 5 by from Awesome!!! I received this bottle for free during a "Stoked on Salt" ocean clean up event. I only picked it out because it looked like a cool container to carry my water around in instead of using plastic bottles. It does an awesome job at keeping things cold. If I put ice in it, there is still ice in it the next day. If I put hot coffee in it, I still burn myself several hours later! I honestly take it almost everywhere with me and clip it to my bag. I use it pretty much every day. I have had it for over a year and have gotten hundreds of refills from it. I have taken it has spent many beach days around Florida, 3 months in Thailand, 3 months in the Maldives, a month in Hawaii, time in Virginia, and a month in the USVI! I am constantly refusing people offering me plastic water bottles and daily disposable cups because I always keep it with me. It has held up well too! I have ruined many other bottles in a quarter of the time. I do get made fun of because I carry it everywhere, but it gives me a chance to educate people about how many one time use plastics they throw away daily and why to reduce and reuse!

    Rated 5 out of 5 by from Absolute Perfect Insulated Hydration Flask! The Hot temperature duration is 8 hours, the Cold temperature duration with ice is 30 hours. This size container will fit perfectly in luxury vehicle cup holders. The top does not have any rubber vacuum seals which is fantastic. This size is perfect and the design is clean and the exterior coating is comfortable to hold. It is a "Must-Have!"

    Rated 5 out of 5 by from I LOVE THIS FLASK! I've tried many water bottles. I have a graveyard of failures. Not this time. The Hydro Flask is awesome! Got a wide mouth 18oz and the straw flip lid, fill with ice in am, add water and make it through the day. I just add cold water as I drink what I have, and the ice makes it all day. Awesome product. I am buying a spare or two now. The the straw lid is secure. No leaks all over my stuff yet, and no condensation problem.

    Rated 5 out of 5 by from Hot or Cold - I am sold on this product. I have two 18-oz wide-mouths - one for coffee and one for water. My coffee stays warm all day at work, and my water fresh and cool. I absolutely love them and purchase them as gifts for others whenever I get the chance!

    Rated 5 out of 5 by from Perfect bottle for weekend adventures! My wife and I decided to give the new Flex Cap a try, and we love it. It makes carrying our Hydro Flask on hikes so much easier and more comfortable. Highly recommended

    Rated 4 out of 5 by from Great product but wide hydro lid leaks Great product but hydro lid leaks. I have the wide mouth 18oz and the lid leaks if you don't tighten the top very tightly, which then you cannot remove later. I upgraded to the wide mouth straw lid and no more leaks or removing lid with pliers. Luckily this works for me in the long term as i'm using the handle to tie it to my backpack with a carabiner

    Rated 3 out of 5 by from Two tiny holes at the bottom. Two days after buying this, I noticed that there are two tiny holes at the bottom of my bottle. Is this normal?

    Rated 3 out of 5 by from Overhyped Bought this mug to keep liquids cold. It says 24 hrs. I don’t think i have made it that long yet. Mostly fill with ice coffee or water with ice. I can leave it on bed stand and all ice melts in 12 hrs or less. I own two less expensive mugs made with same 18/8 steel and they last 40 plus hours. I do like the outside finish amd the grip. It won’t slip out of my hand.

    Rated 3 out of 5 by from Sell the O-ring gasket separately! Love my hydroflask, but I'm looking for something new, as I refuse to buy a new lid every time the wimpy rubbery gasket/ o-ring gets lost or yucky! Come on Hydroflask just sell the gaskets separately and you'll have me buying these for everyone I know! Would abslolutely give 5 stars if I could purchase the rings separately.

    Someone asked about the difference of coffee flask vs regular hydroflask and customer service answered nothing but the cap. But the description says the coffee flask keeps hot beverages hot for 6 hrs and hydroflask keeps it hot for 12 hrs, so which is it?

    Asked by: Moonpie
    The flasks are the same. The difference is in the cap. The hydration flask has a better insulating cap in the flex cap, which is what gives the time difference.

    The straws fit into the 32oz but not the 18oz tumbler. Why do you sell a straw lid and not a straw that works in this cup?

    Asked by: Cms1221
    The straw cap would fit any wide mouth flask. Including the wide mouth 18 oz flask. The straws just have to be cut down to size and there is a cut guide on the back of the package.

    Are they dish washer safe? Can the 18oz wide fit in a car cup holder?

    Asked by: Maddie11
    We do not suggest putting your flask through the dish washer. For cleaning, we recommend hand washing with a bottle brush and mild dish soap.
