The Under Armour UA KNIT TRACK boys' set is made of smooth tricot knit for added durability. The material effectively wicks sweat and dries quickly, while the soft inner surface provides warm comfort. The jacket has a front zip fastening, sleeves with side stripes, ribbed cuffs and hem, and in-seam pockets. The tracksuits have an elastic waistband, side stripes, a tapered fit, and in-seam pockets.
