  • Wide Mouth Flex Cap is rated 4.2 out of 5 by 125.
    Rated 5 out of 5 by from Perfect leakproof This cap is much better than the flip cap; which leaked. With this cap I have to remove the lid each time to take a drink from the bottle. Five stars would be a HydroFlask flip cap lid that does not leak. I would recommend this lid.

    Rated 5 out of 5 by from Keeps hot things hot and cold things cold!!!! I really like the wide mouth on this thermo flask. While it's not good while driving, it's the best while at my desk. It has helped me consume more water daily. It really does keep hot things hot and cold things cold!! Very solid construction. I did read it is best not to put it in the dishwasher so be mindful of that.

    Rated 5 out of 5 by from The best Love this bottle. I have to say I own a lot of items from Hydroflask and I love them all. This one keeps my tea warm all morning at work, and keeps water cold all day on weekend adventures. The only thing that could be improved upon is they do have a propensity to dent if dropped onto any hard surface - i like to think it gives them some added character.

    Rated 5 out of 5 by from Love the cap! Love the wide mouth flex cap! Fits perfectly on my bottle, and keeps my hot drinks hot and my cold drinks cold. Bonus points for the build-in handle, perfect for clipping onto my bag when I'm on the go.

    Rated 5 out of 5 by from Great item The wide mouth flex cap is a great item, it fit on my bottle nicely and does not accidentally pop open nor does it leak! I think I may buy a few more! I like how it’s not hard so if you accidentally bump it with your teeth it doesn’t hurt

    Rated 5 out of 5 by from Great Lid! I have one Hydro Flask and another brand of metal water bottle. The lid on the other brand broke. Luckily, the Hydro Flask lid I have fits, so I ordered one for the other bottle. I like that the lid has a built in handle and that it is so durable!

    Rated 5 out of 5 by from Hydroflask Hydroflask are my go to drink container for keeping water cold in the hot sun. You can go wrong with Hydroflask and they last for a very long time. This is my second hydroflask and I really like the handle on the lid which makes carrying it around very easy. This is also a nice size because it fits in most car cup holders.

    Rated 5 out of 5 by from Can’t live without! I absolutely love my wide mouth flex cap Hydroflask! It goes with me everywhere. The easy to grab flex cap makes it a breeze to pull out of the backpack or my diaper bag. It also works well clipped to my backpack handle with a carabiner. It keeps my water ice cold all day while out running errands or on adventures with the family.

    Rated 5 out of 5 by from Keeps cold! I’ve noticed that this cup keeps my ice water colder than usual. And I love it! I wish the bottle was a bit bigger but it’s fine! It keeps everything I put in it cold overnight and even keeps stuff hot. I love this cup!

    Rated 5 out of 5 by from Great Hot and Cold Thermos I got the Wide Mouth Flex Cap Black a few weeks ago. I have used it to put hot and cold beverages in in. I was surprised how my hot tea stayed hot for many hours. My cold beverage was ice cold for a very long time. Cleans very nice and great product!

    Rated 5 out of 5 by from Very functional I have been a fan of Hydroflask for quite a while but this is the first lid I've found with a handle. With two kids under 6, the handle is awesome! It's a flexible material so I can easily carry it with one finger while juggling everything else. And it seals perfectly like their other lids. My kids have dropped it multiple times with no leaks!

    Rated 5 out of 5 by from Great Bottle I bought this bottle and I'm so happy I did. It's great to take to the gym with me. I love that my water stays cold in it the entire time I am working out. I highly recommend this item to anyone looking for a quality item for on the go to keep their drinks cold.

    Rated 5 out of 5 by from Great lid It feels very premium compared to other brands lids. I’ve traveled with a full water bottle and I had no leaks. Really like the handle as it’s helpful when I carry the bottle through airports and such. I’m happy to now have multiple different lid options that I can use with my Hydroflask.

The product can holds the hot liquids hot for a long period of time, I poured coffee around 7:00 A.M. in the morning and by 2:00 P.M. it was still the same temperature. The cold liquids were also cold for a long period of time. I really love this product and i will recommend it to anybody.

    Rated 5 out of 5 by from Keeping Cool Loving this Wide Mouth Hydro Flask,easy to use easy to carry while going for a walk or to the gym, my water was cold and kept ice the entire day, what I really like the most was the wide cap easy to drink from for myself i prefer a wide top. I did drop a couple time so it's very sturdy had just a lil scratch but no dents to my surprise, overall great product.

    Rated 5 out of 5 by from Must have! This is a must have. I was so impressed with how well it kept things cold. Also it did not sweat and for me that is an absolute must as I usually keep my drinks right next to my computer. Another great feature is the lid and neck. I appreciate being able to put the bigger ice cubes in it without having to struggle. All in all I would definitely recommend this.

    Rated 5 out of 5 by from Convenient I have the black cup with a wide opening. I work a lot of 16 hr days and this cup works great at keeping my drink at the right temp. I don’t have to worry about my drink being watered down and it holds ice for hours. It has a handle which makes it easy to carry when my hands are full. It also works great for coffee and other hot drinks. Overall this is a great cup.

    Rated 5 out of 5 by from I love it! I just love this Hydroflask! It's the perfect size. My husband has stage 4 lung cancer and is going for chemo treatments. His favorite thing right now is crushed ice, as it really helps his throat. This Hydroflask is perfect to put his crushed ice in for our trips to the cancer center. He is able to use it for the whole day and it keeps his crushed ice just the way he likes it. Such a huge blessing for what we are dealing with. When we got home after being gone the whole day, I looked inside and none was melted! This is an amazing product!!

    Rated 5 out of 5 by from Great Product Received this item and I use it every day. I place my coffee in it in the mornings and in the afternoon I fill it with ice water. It keeps my coffee hot just like it was when I poured it fresh. Ice does not melt and my water is cold all afternoon. This replaced my normal everyday cup container for sure.

    is this lid for a 40 oz hydro flask?

    Does this cap fit a Hydro Flask 18 oz.18/8 model F14262 flask?  I lost the cap to mine and need a replacement.

    Asked by: Flip1
    This would be the wide mouth flask. The 18 oz can be either the standard mouth or the wide mouth flask. If the threads are on the outside of the flask it would be a wide mouth. If the cap threads inside the flask, it would be a standard mouth flask.
