Rated 3 out of 5 by from Great Kanteen, Bad Cap I love my Kanteen, however the cap collects mold and gunk inside where the stainless steel meets the silicon seal. You can wash it, scrub it, dish wash it, even soak it but it will still be there. I wish Klean Kanteen can sell the silicon seal by itself. Having to rebuy an entire cap and throwing away the old is just bad for the environment and goes against their whole "Clean and Earth Friendly" motto. If you don't believe me, next time just look at whats floating in your Kanteen.

Rated 5 out of 5 by from Regarding the silicone gasket I had an issue with a gasket coming out of this style cap. Without the gasket, the bottle leaks so I emailed Klean Kanteen and they sent me a dozen gaskets, free of charge. Awesome company!

Rated 2 out of 5 by from really hard to remove odor This is the lid that came with my 16 insulated wide-mouth Klean Kanteen. The lid leaks unless tightened down so tight that I can barely reopen it. I originally thought the problem was with the silicon gasket, so I wrote to Klean Kanteen and they sent replacement gaskets. It still leaks unless tightened incredibly. The worst part is that it's really hard to remove the odor from the lid. Scrubbing and soaking help somewhat. A 24-hour immersion in baking soda help the most, but is impractical on a daily basis. So now I'm stuck with a nice vacuum container that I hate to cap.

Will this cap fit a Hydro Flask 40 oz wide mouth bottle? I lost my Hydro Flask wide  mouth looped screw cap and Hydro Flask does not offer a replacement. I bought a Hydro Flask flip top cap but I want a water tight cap with a carrying loop.
