Thank you for viewing. It has stretch. The lining is made of warm material, but it's thin, so it's easy to move in. There are no scratches or stains, but there is some slight abrasion on the back pockets, etc. There is no abrasion on the knees. Self-inspection, stored at home. Thank you. - Color: Black - Style: Slim fit - Pockets: Back pockets - Waist: Waistband
