After a few weeks with both the PU leather and the silicone VR cover gaskets. I must say I like the silicone one more then the PU leather one. The silicone just feels better on the face, and it's super easy to clean.
The default face gasket is shit compared to both. If you gonna buy the PU leather one, atleast buy a silicone too just to try it out, it might surprise you.
