ASICS M size jersey pants. The lining from the knees up to the waist is lightly brushed, and the lower legs have mesh material with zippered hems, so they are both warm and breathable! I've worn them about 3 times, and they are clean with no wear or stains. - Brand: ASICS - Color: Navy/Blue - Features: Mesh material with zippered hems Thank you for looking. Size: M
