Game Used Michigan Wolverines helmet from 1983.  The helmet is a rare BIKE AiR Power model.  You've seen many Schutt Pro AiR II helmets sourced from the M-Den in the early 90s, however there are not many BIKE Michigan helmets that have survived.  This helmet shows moderate wear on the exterior and interior of the helmet.  Photo above show a patch of missing paint - down to the GB gold shell.  Helmet has its original 80s Riddell OPO mask and original Pac3 style chinstrap.  The AiR Power helmet is complete with the double air bladder and BIKE "handed" jawpads.  The helmet has a #10 identifier written above the earhole on the inside of the helmet.   An excellent, rare, model helmet at a great price.
