Klean Kanteen Stainless Loop Cap

The thing fits but it looks like it was not ment to be on the bottle. Def aftermarket and NOT klean kanteen OEM. I know they are hard to find but I would reccomend you get one from klean kanteen.

After reading some negative reviews about the steel cap, I ordered my bottle with the poly cap instead. I was quickly unsatisfied with the poly cap because it retains the smell of whatever soap you used to wash it. I then ordered the steel cap and I found that it was far superior.

Not only does the steel cap wash cleanly without any residue or leftover smell, but it actually covers the entire lip of the bottle opening. The poly cap does not and it leaves this part exposed. This is important because this is where your lips are actually touching when you drink from the bottle.

I only hand-wash my steel cap, so I haven't had any of the water-retention problems that I've read about in other reviews.

Great cap - if you're going to invest in a stainless bottle, go the extra mile and get the stainless cap, too. A bit pricey, but it's worth it.

I like this a little better than the stainless/plastic one that originally came with my Klean Kanteen. Unfortunately, like the stainless/plastic cap, this cap gets some water trapped inside it when washed in a dishwasher--maybe not quite as much with this one, but I can hear it sloshing around in there when I shake the cap.

This cap is all plastic (polypropylene, which has a fairly safe reputation at this time.)

Unlike the plastic loop-top cap, this one has a a texture around the edge where you grip it to tighten or loosen it.

I like this cap better than the stainless/plastic one that originally came with my Klean Kanteen. This cap is simpler, all plastic (polypropylene, which has a fairly safe reputation at this time.) Easy to wash, goes through my dishwasher in the silverware basket with no problem.

While the original has the advantage of minimizing plastic contact with the water, it somehow gets water trapped inside it if washed in the dishwasher--but then it's very hard to get that water back out. Also the all-plastic flat caps I bought get water trapped inside them. But this cap seems to have a design with no place for the water to get trapped. Another reviewer complained about water getting trapped in this cap. Either
1) he has it confused with on of the other caps (flat top or stainless/plastic)
OR
2) they changed the design of this cap between when he bought his and when I bought mine
OR
3) I've just been lucky so far.

The one way I think this could be improved would be to have some sort of texture around the edge of the cap to make it easier to grip for tightening and loosening. As it is, the surface there is a bit too smooth; so if your hands are wet, weak, or greasy from hand lotion or fried chicken you kind of have to stick your finger through the loop to get leverage. (The flat-top plastic cap does have a texture there that makes it easier to grip.)
