In the winter, I will wear top layer up to 4 or 5 times, depending upon if they get visibility dirty. Like mud or a lot of salt from the road. Base layer gets changed every day. I will wear snow gear as well, most days, and I feel that it protects it. Top layer that is. Socks and underwear every day, year round. Somer time, depends on how sweaty I get. But not more than twice.
