Rated 5 out of 5 by from FULLY LEAKPROOF (adjustable!) This cap has been PERFECT! No leaking, even after a whole lot of jostling in my bag on my bike. It's important to fully tighten the nut on the bottom of the cap (it tightens the rubber seal, it's also how you take it apart to clean it). My friend's cap was a little loose (he didn't notice when he bought it...he's not big on reading instructions...) and I tightened the nut for him, and it's bombproof now!

Rated 5 out of 5 by from Leakproof! This looks like the original cafe cap from the outside, but it is totally different. It has a silicone disk mechanism on the inside to close it off, and it is 100% leakproof. I routinely fill my bottle with carbonated beverages, and even those don't leak when shaken, inverted, or stored sideways. It's great. I have two, and they both perform great. Cleaning them is easy too once you figure out how to take the lid apart and reassemble it.

Rated 5 out of 5 by from Makes an effective product even more pratical I have enjoyed my insulated Klean Kanteen stainless steel bottle but never really liked the screw off cap that it came with. Now, with this "cafe cap" it's a lot easier and more practical to use. I also didn't like drinking from the steel mouth so this cap also solved that dislike. Also, this seems an innovative design and it doesn't leak.

Rated 3 out of 5 by from Not as reliably leakproof as advertised I bought a bottle that came with this lid because I like my non-insulated Klean Canteen bottle but I wanted an insulated version so that I could have a hot coffee break towards the end of a day of kayaking. I knew this thing dribbled a bit (not as advertised) but thought it would be a significant concern. However, when I reached back into the day hatch after a few hours of flat water paddling (a little rocking perhaps, no rolling), my Klean Kanteen was completely empty. I bought another wide-mouth cap hoping that the first unit was faulty but it also leaked just as much. I disassembled and re-assembled 3 times, not knowingly doing anything in particular and it seems not to be leaking now. Anyway, this is a great unit if you can get one with a non-leaking lid, or if you can get a new one to work correctly. But can't give it anymore than 3 stars given the travails I have gone through to get this to work the way it is advertised to work straight out of the box.

Rated 5 out of 5 by from it IS leakproof to the person that says it isn't - maybe you got a faulty one because it will NOT leak. I have the version before this one as well, and it sucks and leaks. HOWEVER - this lid is really only good for water or coffee or THIN beverages...i made a smoothie and could not drink it out of this lid - it is too thick. just an fyi....

Rated 4 out of 5 by from Does the job Does the job but will leak a little bit if it gets tipped over. The regular cap also leaks a little bit too so I kind of expected that.

Rated 3 out of 5 by from Useful, but here are two design improvements... I like it, but I'd like to see v 3.0 with two additions: 1) a handle (I miss that from the original. A swinging version would do the trick) and 2) a color to show when the lid is open or closed. The drinking hole appears to be black, either way. That leads to mishaps, as I have found.

Does it work better than included Cafe Cao with Klean Kanteen 16 OxzWide Vacuum Mug for coffee? Is the cap insulated to keep heat in the bottle better?

Asked by: Tagish
​This is the same cap used on the Klean Kanteen Wide Vacuum Mug with Cafe Cap 2.0. Although not directly insulated, this cap will help retain the heat of your drink.
