This is an all-season jacket equipped with a removable, breathable, waterproof liner and a thermal liner. Aluminum sliders are attached to the shoulders. Hard-type protectors are equipped on the shoulders, elbows, and chest. A soft-type protector is equipped on the back. Purchased new in May 2025. Used less than 10 times. The breathable waterproof liner and thermal liner are unused. It has been washed once. Please refrain from purchasing if you are concerned about very minor scratches. The seller, who is 170cm tall and weighs 75kg, found the fit to be just right when wearing it over a long-sleeved shirt. It is a tighter fit than other Komine jackets. I don't think there's much room to layer clothing under the jacket.
