Jerseys, I have quite a few that I have accumulated over the years. My favorites are ride commemoratives. The others I mostly picked up cheap. T-shirts get clammy and heavy. I want that wicking fabric, zip neck and three back pockets.
Riding nekkid is no good. Sweaty flesh sticks to a leather saddle. Don't ask how I know this.
