These Track Pants from Adidas are made with 100% Polyester twill and pin-tucked seams on the front legs. The black track pants are a collaboration with Song for the Mute and feature an elastic waistband, side pockets, a zippered back left pocket and an open back right pocket. A 3-Stripe panel runs down each side, and a printed wordmark and Trefoil sit under the side pockets.
