The Slim Gym Sweatpant in Black by National Athletic Goods is made from a 100% cotton in a medium weight 11 oz. Japanese loopback terry fleece. Developed with classic mid-century American sportswear in mind, it's constructed out of Japanese yarn knit into a true mock twist mélange to create a soft textured, saturated speckle black with tonal depth. Designed as a functional athletic piece, the Gym Pant comes with slash front jersey lined pockets and a single back patch pocket. Further, flat-locked seams, a contrasting medium grey ribbed waistband and hem, and a woven cotton drawcord give this piece the character you would expect out of a vintage garment. With meticulous yarn development paired with historic inspiration, National Athletic Goods manages to create timeless basics with quality one can feel upon first touch. Generated with traditional production techniques but designed for the modern lifestyle, this sweatpant can transition easily from a day lounging around the house to working out in heritage style.
