  • Wide Mouth Flex Cap is rated 4.3 out of 5 by 130.
    Rated 5 out of 5 by from Exactly What I Wanted My Hydro Flask was given to me second hand with a flip-straw lid. I am not big on straws or those types of lids and to my satisfaction Hydro Flask sold lids separately. I bought the regular screw top for something sturdy, leek proof, and insulating. It works great!

    Rated 5 out of 5 by from Sturdy and keeps its seal Lid feels like its made well and one of the things that stands out most is that it keeps its seal. With other waterbottle lids they constantly start getting mold or the rubber seal completely comes out. That's not the case with these lids. Also, love the handle!

    Rated 5 out of 5 by from Amazing I got this a month ago and I love this water bottle and it kept water extremely cold and hot. I love the water bottle so much. I had so many people come up to me and ask where I got. Of course I told them.

    Rated 5 out of 5 by from great fit I lost the original cap to my hydro flask somehow? I was bummed and wondered if I bought another one, would it be a tight fit and not leak? any wide mouth lid should fit any wide mouth bottle, right? I am happy to say it fits perfect and there are no leaks!

    Rated 5 out of 5 by from Excellent sealant I don’t prefer using straw, so I love this cap! Seals extremely well—no leaks! I like the handle on top too—flexible and very study. The lid is also insulated so it doesn’t just leave the job to the canister to do the job. I’ve had to be careful when I put hot tea in cos it stays hot for so long! You definitely get what you pay for.

    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.

     If used on a 16 oz HydroFlask widemouth coffee flask, will this cap be leak-proof? 

    Asked by: Clara Q
    None of our caps are advertised as leak proof, but this cap is the best for travel. As long as the cap is on properly and the gasket is intact, the cap should not leak.

    Is my cap handle suppose to not be moveable because my handle was not moving which made me drop my 40 oz. hydro flask. Which in turn slightly dent the bottom and crack the paint.

    Will the wide mouth flex cap fit the kids wide mouth, and will it leak if turned upside down with the kids flask? Thank you.

    Asked by: Matilda
    The wide mouth flex cap will fit the 12oz wide mouth kid’s flask. Our lids are not advertised as leak proof. If you turn the flask upside down with the flex cap on it, it should not leak as long as the gasket is in place, and it is screwed on properly.
