I purchased these a few years ago and used them for hiking twice. They are in good condition with no noticeable stains. Perhaps because they are a foreign size, I usually wear a size L, but the M size fit perfectly. (180cm tall, 70kg) These softshell pants provide excellent temperature control and mobility in low temperatures and high-activity situations. They are moderately thick, with durable Kevlar patches on the knees and hips. Recommended for use in the Alps during the late snow season. 【Features】 ● Softshell ● Durable Kevlar patches on the knees, hips, and inner cuffs ● Zippered side pockets ● Zippered leg pockets that do not interfere with harnesses ● Zippered gussets at the cuffs 【Fit: ACTIVE】 Slim fit.
