FREE KNOT FOURON Body Grid Down Pants Men's L Color: Black These pants are warm thanks to their Kohden-shi (far-infrared) technology. The area above the knees is down-filled, while the area below the knees is made of jersey fabric for ease of movement, with a Kohden-shi lining. Due to the nature of Kohden-shi, it tends to pill, so the lining of the seat and the hem are as shown in the photos. No holes or snags are visible. Please see the third photo for the size. For reference, I usually wear size L clothing, and these are a perfect fit in size L as well. Please understand that these are used items before purchasing. Thank you.
