  • Wide Mouth Flex Cap is rated 2.5 out of 5 by 21.
    Rated 5 out of 5 by from Much better cap. My initial Hydro flask had the older cap and the second one this type cap. One day I dropped the orginal bottle and the old style cap split and was no longer of any use. This new type cap is in my view far better. One thought however. If you could offer a lanyard that could connect the cap and the bottle neck, it would be even better.

    Rated 5 out of 5 by from Easier, better cap! Love my flex cap. Fits perfectly and no leaks. So much easier to carry than the regular cap. Perfect!

    Rated 5 out of 5 by from This is a true upgrade I love this cap! It's quite an upgrade from the first generation. It feels more solid, higher quality, and more durable. And it looks really nice too. I haven't had any problems with it, like some of the negative reviews. I received this cap after my first gen cap broke and HF sent me this one as a warranty replacement. Thank you for standing behind your product!

    Rated 5 out of 5 by from Love my HydroFlask! I'm so pleased with my hydroflask! It's perfect because I love COLD water throughout the day & I love that it doesn't sweat and leave a ring of water on my counter! It's perfect :) I'm about to purchase my second one!!!!

    Rated 4 out of 5 by from Great product but has started leaking The bottle is working great and i love now having to fill a water bottle 3 times a day but recently the cap has started to leak and its not great. If I have it in my bag on its side it leaks and it can get really annoying.

    Rated 4 out of 5 by from Easy to Carry Love this style lid because it makes it so easy to carry on a hike or walking! Can also attach a carabiner onto it and attach it to a back pack of other pack! You do need to wash frequently as mold can gather in the corners of the lid. Good product overall.

    Rated 3 out of 5 by from great until rubber ring falls out Love the wide mouth bottle and the cap is very functional. However, once the plastic ring comes off, it's near impossible to secure it back to the cap. Since the cap doesn't seal and the bottle starts to leak. I wish Hydro Flask would take the lid back for repair or offer some tool to put back the ring. It's not environmental friendly to have to buy a new cap every time the ring comes off.

    Rated 3 out of 5 by from Moldy I love my hydro flask and have had it for well over a year. I have to keep purchasing new lids as cleaning them is IMPOSSIBLE. The creases in the lids get so gross.

    Rated 2 out of 5 by from Great but the rubber on the inside is peeling :( I got a flask with this cap as a gift, but less than a year into using it, the rubber on this cap started peeling. Who knows how long I've been drinking rubber for? It has been an ongoing problem and most of the rubber has peeled off by now. I will be contacting hydroflask for a replacement soon.

    Rated 2 out of 5 by from Inner piece keeps getting mold I have gone through 2 wide mouth caps and the rubber seal piece keeps getting moldy. When I take out that piece not all the mold comes off of it....

    Rated 2 out of 5 by from It's ok, needs improvement. I got a customized yellow widemouth lid and bottle(green 32oz) from my girlfriend and I thought it was great! Only problem is that after the rubber seal fell off my lid my hydro flask does not provide the same effectiveness. It does keep my drinks cold or hot any longer :( I don't want to buy another because I don't need it, but I do wish they would make them better.

    Rated 2 out of 5 by from It leaks! This replacement lid leaks and it's worth the money.

    Rated 2 out of 5 by from Cap gasket falls out I bought an 18oz bottle with a flip lid for easy drinking but realised it doesn't keep the water warm for very long when I went trekking in the Himalayas a few years ago. So i just started using it as a normal water bottle for warm water in the office. Then a few months ago, the gasket fell out and I didnt notice until a few days after. Now it doesn't keep my water warm and it leaks! Had to dry out the contents of my teaching bag the other day after a leak. Man... You got to make sure the gasket stays in. Not gonna recommend this to anyone.

    Rated 1 out of 5 by from Gasket comes loose just after a few days It's a nice looking but horribly dysfunctional lid. I've just bought a wide mouth double-walled Hydro Flask and while the flask seems very well-made, the lid is poorly designed. I don't get the 'Reddot design award': is that just an award for looks? Because otherwise, I don't think this jury hasn't used the lid for a little while... The gasket inside the lid comes easily loose, sometimes gets back into position after screwing the lid on, and then...comes loose again. Not to mention that this is potential food safety hazard: if you pour juice into the Hydro Flask and some juice gets beneath the lid...hello mould! Remember, I just got this for a couple of days and it's not like I've been treating it unkindly. I dearly wish Hydro Flask will come up with a new lid soon enough, one that's reliable. I can really see myself growing very fond of my Hydro Flask with a better lid!

    Rated 1 out of 5 by from Fell apart the first day of use! The first day of using this cap, the plastic ring stretched out and now it leaks. I’ve emailed the company twice and have not received a response.

    Rated 1 out of 5 by from Please come up with a solution I have many hydro flask products: -true pints, 22-oz cups, the 21-oz bottles (with sports and standard lids), 40-oz wide mouths (original lid), and two 64-oz (the newest, and previous versions that use wide mouth lid) They all work great! I used to think that the bottles were retaining the smell but it turns out that the LIDS are the problem. all the lids I have for my hydro flasks retain smell and mold. I have bought many extra lids and they cannot be cleaned either. the plastic seal came off one of my lids and I threw it away to get another one. There aren't any helpful tips on cleaning instructions. I have tried everything to clean my sports cap, standard, and wide mouth lids but they all have a sticky mold-like substance on them that is IMPOSSIBLE (even with a mascara applicator brush) to clean! -provide a video or something please...

    Rated 1 out of 5 by from Rubber Gasket Nightmare I have had the rubber seal/gasket fall off super easily when I open my drink. I have to adjust it every time. It is supposed to be taken out so it can be cleaned behind it, but cannot be placed back properly - leading to many spills and leaks on my clothes and backpack. I have tried the flip lid too, but that seems to pop up too easily and spills all over as well. SO OVER THIS PRODUCT! Make a better option please - and replace my lids.

    Rated 1 out of 5 by from can't clean well My 14 year old daughter uses this hydroflask almost everyday. Even though I wash/rinse it every morning and refill it because the hydroflask is almost always wet it gets mold growth inside the cap and it's impossible to clean inside the deep grooves. Since this is such an expensive product I would expect it to be made better so that you can completely clean it.

    Rated 1 out of 5 by from Leaks and does not keep water hot I have two 40 oz HydroFlask insulated water bottles and discovered this cap seal comes apart when hot water in the container. I was hoping to use these insulated water bottles for winter hiking in the White Mountains, NH. As a result of the leaking lid, hot water leaks out of the container, leaks hot water over my back and then freezes bottle to the backpack. I have tried several times to reset the seal in the lid but continues to come apart and leak. The lids are adequate with cold water.

    Rated 1 out of 5 by from Falls off and leaks! My husband and I have 2-32oz, 2-21oz,and 1-24oz. I’m resisting the urge to get myself another 24oz one bec of the caps. My 32-oz with the 1st gen wide mouth cap could not be opened because the gasket kept getting caught. Hydroflask told me that this happens when the bottle is filled past a certain point. I was sent this as a replacement and I absolutely hate it! It has come off multiple times when I pick it up from the loop. It’s not fun mopping up the floors or drying off my car seat! It also leaks...I’ve found my gym bag and clothes soaked multiple times. I love the hydroflask bottles but I think they still need to work on the design of their caps.

    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.
