    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 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 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 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 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 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.

    Rated 1 out of 5 by from Grip on lid is lacking - too smooth... Have older HFs for comparison. These newer lids with the smooth plastic and rubbery handle make it difficult to get a nice grip on opening and closing the lid. The slight texture on the older caps made it much easier to open/close. Hope you can address this as it poses a problem for baby-boomers/older users and disabled. Thanks

    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.
