Klean Kanteen Poly Sports 2.0 Cap

Hi. I am looking for a sports cap that will fit my Sub-zero 750mL Stainless steel water bottle. I was wondering if this will fit on it. Since this cap is good looking, I would want to buy it, but don't know if it'll fit with my Sub-zero stainless steel water bottle. Please help. Thanks.

The sport top plus the eye-hook handle is a nice feature but the cap leaks when tipped sideways. The product packaging gives a leakage disclaimer, but I wasn't able to read that disclaimer until after I purchased this product. We just need to make sure our kanteens stay upright now, and with two younger children, that's not always easy to do.

I loved the idea of a cap because I hate to drink out of the wide mouth. But this cap leaks terribly! It does not leak out of the mouth spout - I pushed that tightly closed, laid it on its side and realized the leak comes from the small space on the side silicone "stopper." This stopper is also the cause of the awful noise when you drink! When i am in class, people around me used to look at me when I drank because of the noise. Now I have to press down on the silicone stopper so it doesn't have to make the chirping noise when I am somewhere quiet. So this silicone piece is round and fits through a straight hole, leaving holes on either side of the silicone. These holes seems to be the cause of the leakage and noise. I hate not being able to lay the bottle flat in my smaller purses - I have to stand it upstraight and only zipper the purse partway to accommodate the bottle. I Wish KK would fix this!

I bought a few extra tops to go along with my Klean Kanteen bottles. Some reviews state they leak, but my 3 and 5 year old kids use these every day and there is no leaking around the threads (rubber ring is tight). If you leave the top up it will leak if tipped, but every water bottle I've had will do that.

I needed it, so I bought it, choking over the
fact that the shipping cost was almost twice the
cost of the item itself.
