They're called warm-up pants for a reason. The perfect layer to get your mind and muscles ready, these adidas track pants are made from classic sport tricot for a smooth look and feel. The drawcord-elastic waist and cuffed hems help them stay in place. Take them off once you're in the zone, and pull them right back on when it's time to head out. The sleek style isn't limited to your workout, though. 3-Stripes are all about versatility.
