How to quiet a noisy cap! This works!
I was almost ready to quit using my cap because it was embarassing to use,no matter how slowly and quietly I tried drinking from it!But, I sent klean kanteen an email asking if they had any suggestions, not really expecting an answer...but I did get an email back with the answer I hoped for. The tip they gave me WORKED, and I absolutely love the cap now, and it doesn't make a sound!So, here's what they sent to me....I hope it works for you too. From Klean Kanteen: "I do have some tips for using the sports caps. They are our most popular cap, as well as our most complained about. It is the air pressure that makes that funny noise.Sports caps were originally designed and used with plastic drinking bottles, and with those, we have the ability to squeeze and change the pressure coming in and out. Because you cannot squeeze stainless steel, air has a more difficult time getting inside and making the water flow out. We had to alter the design to include an...

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...
