One 5XR owner from the IL-2 forum purchased a set in Aliexpress for VivePro.
Says ideally suited for Pimax:
I bought myself such a set of facial pads
It fit perfectly in size, settled on the thickest one, just a little bit distanced from the lenses and it became just super! [
Well, for the care of the lenses a great set
I recommend for Pimaks in general :))
I really like the thickness of 10mm my native face pads in my 8K.
But it puts a lot of pressure on my forehead after a half hour of use, a sharp corner, leaving one deep mark.
Therefore, I first tried the faceplate from the OG Vive 10mm.
She sits on my face very well, very comfortable, no more pain in the forehead. But there is a problem, it will badly fit on my 8K, because it is too small, it has to be twisted a little, otherwise the lower ends cover the bottom of the lens.
I made the measurements.
The width of my native faceplate Pimax is 23cm.
And the original foam for OG Vive has a length of 21cm (I saw this in the description on Aliexpress.)
But a VivePro has a very suitable 23cm
I could not resist and bought this kit on the advice above.
So the face pad from VIve Pro should be fine
