Two awesome pairs of athletic pants, hardly worn. The dark gray are an extra small, semi fitted. They have a pocket in the back of the waist and a straight leg. The light gray pants have a looser Leg they are a size small. The light gray pants have a drawstring in the bottom of the pant so that you can tighten them up, I would think to keep them off the ground when you're running. Inseam on xs is 30, on small is 31.
