J62 holding up nicely, also used with 3a regularly. Giving how strangely fragile it feels to the touch and how thin it is, that's a bit surprising. I wouldn't recommend scraping along a rough wall, running into sharp corners or objects or falling with your bike wearing it.
Edit: what the material will do definitely is showing tiny creases all over the place, even if it's new. They're smoothed out with pressure/support applied, but looking closely it's a mix of wrinkly and smooth with a dull sheen with the pattern of the base fabric occasionally showing through in stripes if it's sitting in a specific way.
