Klean Kanteen Classic Steel Loop Cap – Leak-Proof, Dishwasher-Safe, BPA-Free – Brushed Stainless

Narrow mouth Klean Kanteen and Hydro Flask bottles are my favorite water bottles and have been for years. The plastic caps they both come with are interchangeable (usually, tolerances can vary a little) and they work fine and are well designed but these all steel caps are way better. Hydro flask used to make the best all steel option but it appears they stopped making them, so this is now the best and only all steel cap I’m aware of. There’s the Klean Kanteen version with bamboo on top but it’s not as robust or as solid as this one. These all steel caps are great because they add a little extra insulation for when that matters (hot/cold) and eliminate the ever increasing plastic exposure in water bottles. Also, these solid one piece caps are much easier to clean since there’s no crevices to deal with which gives bacteria a nice little home to grow and smell. Pro tip on water bottles btw, don’t put anything in them but water and they won’t get gross and smelly ;)

I was wanting the older top but this newer one is more compact & all metal. Now I like the new one better.

I have bought (and accidentally lost) several of these stainless steel caps. I'm trying hard to get plastic out of my life as much as possible, so this cap is a great alternative to the original plastic cap that comes with the classic Kanteen bottles. These caps also fit some children's water bottles.

Very easy to clean and functional. The loop on the lid is a little painful to use if you over tighten the lid, but you can slip a spoon handle under it for torque.

Great cap for my Klean Kanteen. No plastic.

Cap works perfectly in years-old canteens.

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.

I have a Aer sling, and my bottle only just fits in. It’s a squeeze. But now with this new lid it fits. And also there’s no rattle from a dangling loop (like the bamboo version I was considering). And I can still attach the bottle via the carabiner to the outside of the bag. The shop I ordered this from posted the item on the same day as I ordered (Sunday) and it arrived Monday morning. Thats fast. Nice one.

Works great with the kleen canteens.

Good cap. Low profile & sturdy.

C’est top d’avoir une option 100% inox.

This lid fit my Kleen Kanteens perfectly and reduced our use of the plastic ones we had, I only wish the top handle wasn’t so small and had softer edges where the fingers could easily get through.
