Khaki-colored phenix shorts, adjustable waist, perfect for the outdoors. - Brand: phenix - Size: S - Material: 62% Polyester, 34% Cotton, 4% Polyurethane - Features: Belt with adjustable waist - Color: Khaki Thank you for viewing. Although new and unused, the tags and bag have been removed, and it has been stored at home. I purchased a different color of the same style at the same time, and since I didn't use these, I'm selling them. These are thick pants. How about them for autumn mountain climbing? They are size S, but I think they would also fit a size M.
