These are trekking pants from Columbia. I've used them a few times for mountain climbing, such as at Mt. Kongo and Odaigahara. They are made of a material with some water repellency and sweat absorption. The size is XL, and I don't think there is any particular damage. Thank you. - Brand: Columbia - Color: Black - Features: Adjustable waist, zippered pockets - Style: Outdoor pants - Material: Nylon Thank you for looking.
