We were required to start wearing jocks in PE class when I was starting Middle School. They came as part of the P.E. uniform, which we bought for a few bucks -- we all had to match colors, of course. First Blue, then yellow, red and blue again. T-shirt (with area to write our last names or nicknames in Magic Marker or whatever), shorts, jock, and a pair of white socks. They provided towels in the locker room. Somewhere, I still have all my P.E. uniforms...though I'm sure I can't fit into my pre-high school ones.
