Customer Reviews

Good product... does what it's supposed to
I recently gave up buying bottled water. While I don't miss dealing with all the plastic bottles, I did miss the sports cap that my favorite brand came with. I was happy to see that Klean Kanteen offers a sports cap, and I am happy that it works just like any other sports-capped bottle I've used.

Like other reviewers noted, my sports cap whistled when I took a drink. Thanks to another reviewer, I discovered that if I loosen the cap just a little, I get a much better flow of water and no whistling. Basically, my sports cap works best if I tighten it just to the point of stopping and then no more. (My habit is to use more pressure and tighten it that extra turn or so.) Even though I leave off that extra turn, I have had no problem with leaking.

Works fantastically well
For the longest time, I held off on buying products like this one after reading several so-so reviews, or the one or two negative reviews in a bunch of good ones. It took me a long time to figure out that the very existence of an opinion forum will invite some people to nitpick, and often to even find problems where none actually exist. Such is exactly the case with the Klean Kanteen Sport Cap 2.0. I own three such caps, and exchange them among three Klean Kanteen bottles. I've never had the least bit of trouble tightening or untightening any of the caps on any of the bottles. Before writing this review, I went to a local store that sells these, and did another check there, exchanging several Sport Caps 2.0 with several Klean Kanteen water bottles. The result: Not a single problem. The caps all fit well, and tightened and untightened easily on every Klean Kanteen of every size that I tried them on. It's always possible that someone got a defective bottle or cap, but I find it difficult indeed to imagine that the average person would have any trouble whatsoever in this department.

As for flow and noise: The Sport Cap 2.0 is designed to increase the flow, and it certainly does. After a long run, I can drain a 27-ounce KK in well under 10 seconds with this cap on it. It's a cinch to wash it, and other than that it requires no maintenance. The only "drawback", if you want to call it that, is the slight whistling sound the cap makes when you drink from it--not some mysterious, strange sound that will make people wonder, but the ordinary sound of air rushing through a small hole in the cap, past a small silicone valve. The noise could probably be eliminated altogether if the valve hole was bigger--but this would make leaks much more likely (as it is, I can shake, drop, run with, and roll my KKs across the floor with no leakage whatsoever from this cap). In any case, I've used my KKs with this cap at work, in the classroom, and even in the quiet zone of a research library and never gotten so much as a curious glance due to this "noise" that is about as audible as a grumbling stomach.

Unless you spend most of your time inside a completely silent echo chamber, the air-flow sound won't be a problem for you, and as my three-year-old nephew can tighten one of these caps just fine, I doubt you'll find that to be an issue either. If you're looking for an excellent, easy-to-use-and-clean, high-flow cap for a KK, this is just the thing.

Solid cap, doesn't whistle if you use it right.
Its a solid sports cap that is designed specifically for KK. The reason it whistles is that the Kanteen is solid steel and unlike plastic bottles you cannot squeeze it to get the water out. You actually have to suck on the cap to get the water out. There is actually a little soft plastic valve that opens when theres negative pressure in the bottle letting air in from the outside. This is what causes the whistling. If you orient the cap so that this valve is on top and not touching the water inside, it wont make that chirping noise. A bit annoying (thus the -1 star) but it isnt something that is a real dealbreaker.
