Worn in spring, autumn, and early winter. There are no noticeable stains or scratches, and it can still be used sufficiently. It has excellent stretch and is easy to move in and comfortable to wear. Both pockets are dummy pockets. Back pockets only. No opening for replacing the elastic. I think the elastic is strong enough. The actual color is a slightly lighter blue than in the photos. Inseam: Approximately 58 cm
