Classic Klean Kanteen bottle are sold with a sport cap, which is useful but not completely watertight (at east mine isn't). This cap allows to store safely the bottle in a backpack or similar even if it ends head over feet.

Stainless Caps retain fluid and RUST! 16 Dec 2008
By D. Johnson - Published on
Verified Purchase
I oredered this cap as an alternate cap to use with the sport cap on my 40oz bottle. Both were ordered from Amazon.

First, the new SS caps are not the same design as the original (on a KK bottle I bought that came with SS flat cap 2 years ago) the knurled edges only go around a portion of the cap and they are not as high in relief, this makes the cap a bit harder to get off, this is just a nitpick. BUT...

The real problem with this cap is what others have mentioned, water leaks inside the cap (between the plastic and SS threaded portion. I read the reviews and decided in advance I would not submerge this new cap. I washed by hand, filled my bottle a left for work. When I got there, I noticed that some of the water I had put in the bottle was now stuck in the cap, I stress that this was liquid from my beverage (water). I don't feel this cap is safe to use, and completely unacceptable - if you fill your KK with different fluids, such as juice, do you really want this liquid staying in the cap to age/spoil and then possibly re-entering the bottle.

The SS flat caps (at least this version from amazon) are a waste of money. I can't say it is the caps fault, but I also noticed rust on the thread of both the bottle and cap - it could have occurred on either one and then transferred to the other so I can't tell which is to blame. Again this was on the first day of using the bottle and cap. My two other KK bottles, one with SS Flat cap (older design) and a newer one with PP loop cap both have never had any problems. KK needs a new design for the SS caps - I would not buy these until this issue has been fixed.

Stainless Flat Cap = Piece of Crap 22 May 2009
By Mister B. - Published on
This cap is so pathetic that it caused me to post my first review.

I was looking forward to using this cap instead of the plastic cap. But it's a piece of crap. Don't waste your money.

The black plastic piece separated from the (hollow) stainless piece as soon as I tried to get a tight seal. There doesn't appear to be any kind of sealant used to hold the pieces together. They just kind of jammed the two pieces together (by lining up two tabs on the plastic part with two notches in the stainless part) and hoped for the best.

What happened to the stainless steel caps? 7 Mar 2008
By Jazzman - Published on
What happened to the stainless steel caps??? They used to come standard. I am not gving the low rating to this cap, but to the fact that they have switched to plastic. The whole idea was to have the internal part of the screw top to be steel, so there's no plastic touching your liquid. The exterior grip on the lid was always plastic - that's fine. But now, you have to buy the original stainless screw cap as an accessory that costs more than 1/3 as much as the entire bottle product.
Shame on you Klean Kanteen.

I have four caps, like stainless steel flat top best 7 Feb 2009
By Josue - Published on
I have purchased the stainless flat cap, stainless loop cap, poly loop cap, and poly sports cap... To my surprise, I find myself using the stainless flat cap more than any other. (I never submerse it when washing). The strongest cap is the poly loop cap. The sports cap works but since you can't squeeze the bottle to get more liquid out like a plastic bottle they had to make a release valve in the cap which works great - BUT squeaks rather loudly. Since I use my bottle mostly at church, work, and public non-sports places, this doesn't work well for my needs. The stainless steel loop top is my second most used top, but seems weaker than the others. However, I have had my tops for several months now without incident.

Needs Improvement 13 May 2009
By J. Howson - Published on
Love the fact that it is stainless steel but the upper plastic portion keeps coming off when putting this lid on the bottle. Perhaps we got a lemon but it is a pain to have to keep putting the plastic top back on and also when it comes off it exposes metal that is sharp.
