Mine look brand new after several wears. I've had mine about 14 months now. No yellowing at all, but I did keep them in the box in-between wears in a dark, climate-controlled closet.
Sole AIO.
I wasn't prepped at all for the Satins. Just bought Sole the night before (unexpectedly) and didn't have a site list or proxies. Went all manual and took L's. lol
