Replacement Lid for Hydro Flask Standard Mouth 12, 18, 21, 24 oz Water Bottles, Accessories for Hydro Flask and Most Sports Water Bottles, Leakproof, BPA-Free

There's not much to say about these -- they're lids after all. However, I just wanted to counter other people's experience with these in regards to the 64oz growler. Not sure if other people got a back batch, poor mold injection or whatever -- or maybe I got lucky. These DID fit both of my 64oz hydro flask growlers and they come with the gasket so there was absolutely no leakage. And I did try pretty hard to get them to leak, I.e. shake the hell out of the growlers and left them upside down over night with liquid inside -- not a drop expelled. They look just like the original ones. So annoying that hydro flask doesn't sell these anymore, what a wasted opportunity for there's clearly a market. Please note also, if these don't work for you, I used the wide mouth lid off of my old nalgene 32oz bottles, and that worked as well. I like these more just because they are a bit more beefy for dangling off the ring.

Let me preface this by saying, I do not own a hydro flask bottle. So, I can not tell you if it works for that. However, I can tell you that it does not work well with a metal cirkul bottle. I had read that hydro flask lids worked with the cirkul and was wanting an option to use my bottle without a cartridge. The only way the lid will work with a cirkul is if you are willing to cut off the loop/handle, otherwise the lid will not screw down tight enough not to leak. Not pretty, but gets the job done. I had a horrible time cutting it off, so good quality there. 😅 I can not fault the product since I did not use it for its intended purpose, so I gave 5 stars.

This is a Chinese-made knock-off that currently (July 2024) costs $5.50 compared to a true Klean Kanteen replacement cap that currently costs $9.95 (also available on Amazon). The biggest—and to me crucial—difference is that the knock-off doesn't have the one-way pressure relief valve that lets you continue drinking without having to stop and let air in to equalize the low pressure that occurs when you remove water by drinking it. When the air pressure drops water won't come out until you let more air in. The Klean Kanteen cap does this automatically with the pressure relief valve so you can just keep on drinking until you've had enough. I bought the knock-off only because I didn't look closely enough at the description, saw the difference as soon as it arrived, and then bought a Klean Kanteen replacement. In the attached photos, the knock-off is on the left and the Klean Kanteen product is on the right. For $4.45 more, get the real thing.

These lids fit my water bottles perfectly. One of the lid handles broke immediately upon use, which was a big bummer; the other lid is holding up ok. The o-ring inside the lid can slip out from time to time. This causes me to have less of a water tight seal or to get the lid stuck on my water bottle so that when I go to open it, I have to pry the lid off the bottle causing me to make a bit of a mess if the water bottle is full.

Perfect fit.

Overall happy with these lids, they fit my old 32oz. Hydro flask bottle similar to the old ones. The gray silicone bands can be moved to the new lids. The silicone seals seem to work. Retaining strap is a little stiff, but it is new still. Hopefully I won't drop these on their heads anytime soon.

I love my sippy water bottle but my sport lid was breaking so I ordered this set. The clear spout one is good, can drink without the straw, the black spout one barely lets any water through, maybe it’s a fluke, but I will keep this just for the rubber bottom thing and the clear spout sport cap. Then randomly the clear spout sport caps handle cracked and is broken, so I’ll be duct taping that and carrying on, put intended lol…………..

2021 update. I got a third one for my new Kleen Kanteen insulated bottle. The new cap hasa stellar finish on the bamboo and is well sanded, so these are even better now. They should not be used to cap boiling hot water but hotter-than-you-can-comfortably-chug is fine. Do not dishwash or immerse. 2020 update: After two years of daily use still great for my Kleen Kanteens. 2018 original review. Perfect for the cost and my function. The finish on the bamboo could be a bit better; it's a tiny bit rough around the edges. I am using these on Kleen Kanteen classic bottles. These are 100% leakproof on those bottles. As far as the 0-ring seal, they seem better designed than the Kleen Kanteen originals Time to pull out the sandpaper and butcher block oil. You must oil the bamboo occasionally, or it will disintegrate like most wood products around water. You can use just a mineral oil, or use butcher block oil, or at a pinch even just rubbing in some coconut oil will have some benefits. Please remember that this product is not designed or advertised as dishwasher-safe.
