Purchased three years ago and used for mountain climbing in the snow twice. Since I have short legs, I had the hem adjusted, so there are marks on the hem (photos 5 and 6). I think there are no functional problems. It has been washed at a dry cleaner. The following is a product description from the internet: Thermal pants that add heat retention to the classic Verb Pants, which are excellent in elasticity and wind resistance. The soft brushed lining is warm, and it uses a stretch material that maintains high stretch recovery even in cold conditions. The fabric is water-repellent, repelling some rain and snow. The thighs have zippered ventilation to efficiently release heat trapped inside the wear during intense exercise. The front zipper has a double slider specification that considers harness wear. With a three-dimensional cut and a tapered silhouette that allows for easy leg movement, these pants are perfect for trekking in the fall and winter. ■Fabric: APEX Aerobic Thermal (90% nylon, 10% polyurethane) ■Function ・Zippered ventilation on the side of the thighs ・Boot hook and eyelet on the hem ・Tapered silhouette ■Country of Origin: Vietnam ■Size: L ■Weight: Approximately 460g (size L) ■Size Dimensions (actual size) L: Waist 78: Hip width 50: Rise 24: Inseam 79: Hem width 19 Thank you for viewing.
