Vintage 1970s Mens Match System Munsingwear Red Track Shorts Size XL 18-20 RARE

Vintage 1970s Mens Match System Munsingwear Red Track Shorts Size XL 18 - 20. Very rare, in good used condition. They are from Munsingwears ‘Match Stystem’ for shorts and underwear. I included a 1978 advertisement image to show the fashion campaign for proof of year. That was pulled from google and is not included in purchase, only the shorts. I’ve never seen another pair of these before. No holes or stains. Very retro. Vibrant red with white line accent.
