I've got a wool winter cap like that, a Butch Martin Protogs brand. Bought it when I worked at the LBS many years ago. Black on one side, reversible to what at the time was an ugly peasoup green & black on the other side. I didn't know that 25 years later it would be a good match for my modern Bianchi.

I also posted in Catch of the Day last month a couple of $3 thrift store jerseys I scored.
