Although there are no specific markings, this jacket is made of Gore-Tex material, making it highly water-repellent and suitable for various situations. The hood is a GEN2 type that can be stored in the collar. Ventilation is possible by opening the zippers on the sides. There are zippers for attaching a liner. Please refer to the tag for detailed size information. I believe the size is between M and L for Japanese men's sizes. I am 170cm tall and it fits perfectly. The condition is good, but it is a used item, so please understand. I think it's hard to come by. Military Survival Outdoor Survival Game
