I wore this twice when I took my child skiing (I don't ski myself). After that, I washed it at home and stored it. There is no deterioration of the rubber, but there is some dirt on the inside of the cuffs (the skin side) (see image 11). There are no other noticeable stains or scratches, but there may be individual differences in how things are perceived and there may be oversights, so please understand that this is a used item and only those who understand this are welcome to purchase. * The hat cannot be removed.
