These are the Nike x Undercover Gyakusou Utility Men's Tights, a collaboration between Nike and Jun Takahashi's label, Undercover. This specific colorway—featuring burgundy, slate grey, and blue panels—was part of the Fall/Winter 2012 "Autumn Monks" collection. Design: These are technical running tights designed with moisture-wicking Dri-FIT fabric and a compression fit. Multiple zippered "utility" pockets on the hips. A distinctive paneled, layered look with reflective strips. Signature "GYAKUSOU" branding on the thigh. Materials: made from a blend of approximately 74% polyester and 26% polyurethane. Some of the best running grea you can buy... while the legs fit like tights, the 'shorts' area is not skin tight, they fit more like running shorts if you dont want you 'tackle' strangled Size M. measures 30" flat
