I collected these in the 1980's up until about 1992. This one is NOS.
This cap is PERFECT as new!!!! The fabric is slightly stiff as new caps always were.
I've never seen another like this in my decades cycling and in the Bicycle business.

I'm a little reluctant to have to sell this one. There is no label on the inside at all.

I will be listing an entire collection of caps in December.
If you have any questions please ask.
