Klean Kanteen Classic Steel Loop Cap - Leak-Proof Water Bottle Lid - Easy Clean & Dishwasher Safe - BPA Free Bottle Cap - Brushed Stainless

I prefer the stainless steal top as I am attempting to avoid plastics. Seal is perfect. Love it.

I purchased a few of these to replace the black plastic ones that sometimes come with stainless bottles. We now know that plastics like this are super toxic and are in constant contact with your beverage. These are from the manufacturer and are very high quality as are nearly all of their products.

Yes you have to unscrew it but it doesn’t leak and you aren’t consuming plastic! Happy with mine.

We got this to replace the black plastic original because we are learning more about black plastic being recycled electronic waste and leaching PFAS and other "forever chemicals" into food and water. We're replacing all black plastic now, and we're glad to find this. It does squeak a bit when turning, no biggie.

Good replacement

Love this cap! Moved from a Hydroflask to a stainless steel finish Klean Kanteen because coloured coatings on water bottles always ends up flaking off in the dishwasher, and water somehow always made its way INTO the plastic hydroflask lid during the wash cycle (I could hear it sloshing about inside the lid), and dripped out slowly during the day, getting everything wet. This cap not only removes all plastic from the equation (yay), but is also completely impervious to water. I just wish they made a full stainless steel cap for the wide-mouth kanteen.

Love it! Fits my ild waterbottle like a charm. For context my waterbottle is 15 years old and nicely battered. I love that it is plastic free except for the tiny leak-proof strip around the lid edge. I had a problem with my last 4 plastic lods with either breakage leading to plastic slivers or bacteria build up that was difficult to clean. No cleaning problems here! And darn near impossible to break too.

This is a great stainless steel option with a silicone ring to ensure a leak-free fit. Unfortunately, I am used to carrying a full liter of fluid by the lid itself with one finger. This lid is definitely not designed for doing so. Maybe in the future they will design one that is as comfortable as the plastic ones are. It also took forever to be delivered - almost 3 weeks. Do not order if you are in a rush.
