This is a 70s Sierra Designs mountain parka. It's made of 60/40 cloth, a Sierra Designs patent. The 60/40 cloth works by the cotton in the weft threads swelling when they absorb water, closing the gaps between the threads and making it water-resistant. This, combined with the water-repellent properties of nylon, allows it to repel water. In other words, the water-repellent function is activated when it gets wet. The size is marked as M, but it fits like a Large. The condition is that there are some light stains on the lower right pocket and sleeves. They are not noticeable when worn. Otherwise, there are no other stains or tears, and the condition is quite good for something that is about 50 years old. Current 60/40 cloth mountain parkas cost over 60,000 yen. I think it's a great deal, so please take this opportunity to consider it.
