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
