These are outdoor pants suitable for camping and summer mountain climbing. Made of a smooth, lightweight fabric, they are perfect for camping, summer mountain hikes, and as a change of pants for overnight summer mountain trips. They are incredibly light and don't take up much space. The knees can be detached, allowing you to convert them into longer shorts. I'm selling them because I've outgrown them. I only wore them a few times, as they were intended as a spare pair. Color: Dark Navy Waist: Elastic Brand: Unknown (purchased at a mountain gear specialty store)
