I just bought one of this at the Thrift Store! It's amazing! It is still in like new condition, manual, rearview mirror, visor and the fit kit! I was looking for a helmet to wear while riding my Cannondale, but I think I'm keeping this Skid-Lid as part of my random vintage items collection! The manual has copyright 1981.
It's older than me! Oh my! It is a cool helmet!
