Matman Doubleknit Nylon Adult Wrestling Singlet: Matman 83 Nylon Fabric THROWBACK LOOK: Matman's #81 and #83 Doubleknit Nylon wrestling singlets are truly "throwback" singlets. As the name indicates, if youre looking for the classic style and look, these old school singlets are for you. 100% NYLON: As the name indicates, it's made of a heavy 100% nylon fabric. This is very different from the more common lycra singlets, which are made with a blend of polyester and spandex or nylon and spandex. STRETCH & GRIP: The 100% nylon singlets have very little stretch compared to the singlets with spandex blended in the fabric. This comfortable singlet stays secure with bare rubber leg grippers. MULTI-FUNCTION: It's reminiscent of the days when Dan Gable ruled the mat, and singlets were commonly accompanied by knee-high socks or legging. This singlet is probably most commonly sought out by competitive weightlifters and cross-fitters. MATMAN WRESTLING: We take great pride in our All-American approach to quality and thats why all our products are made in the USA - never by domestic or overseas contractors. We know youll notice the Matman difference!
