The ATHLETIC ZIPPER HEM PANTS are heavy cotton jersey sweatpants, with a zipped side opening — trimmed in U.S. team colors from the all-military Olympic pentathlon squad - worn while competing in Helsinki, the first post-WWII competition.

The Heavy Cotton Jersey fabric is cut to a vintage fit and can be secured with a drawstring closure.

An early innovation in sportswear, the side seam zip allowed sweatpants to be easily removed over boots after warm up.
