This is a late 70's Red Zinger Bicycle Classic trucker hat from Boulder, CO. This race would later be Coors International Bicycle Classic from 1980-88. This trucker hat is original. It does not hold it's shape that well due to it's age (it flops unless it is tight on your head). But overall, this hat is still in great shape. No holes or threads coming apart. The adjustable back still works great. There are some old sweat stains along the inside brim.
