Does this also fit the Simple Modern Trek 40oz tumbler?

Yes, fits very well, exact fit.

Dose it fit Stanley 3o oz adventure quencher?

I just tried it on my 30oz and yes it does fit

Anyone have issues with it fading the finish of your cup. Mine now has a colored ring like it's transferring color

I don’t have any fading issues. I do remove the silicone sleeve before I wash my Stanley’s either by hand or in the dishwasher

Nice protection.

Fit nicely on my 40oz Stanley. I love how it doesn’t clang when I put it down anymore. I’m not afraid of it slipping off things. I really enjoy these.

Easy choice

Great plastic covers for Stanley or equivalent. They are a white-ish color. I love this product because it keeps my very large cup from banging and clinking on the counter. Great price makes this an easy choice!

Gamechanger for bottoms

Gamechanger for bottoms, tired of "pinging" countertops or desks. I little tight in cupholders, but that's the trade off.
