This is a very popular vintage coat, a P-coat by HERCULES. It's likely from the 1950s to 1970s. I bought it from a vintage clothing store four years ago for 58,000 yen. There's some damage in places, but considering HERCULES coats, especially those with quilted linings, often have significant damage, I'd say the condition is pretty good. The color is a beautiful red and black check, with a great color scheme. I'm 172cm tall and weigh 62kg, and it fit me with a little room to spare. I think someone between 175cm and 180cm would find the length to be just right. There's no size tag, so I'd estimate it to be a size L, but if you'd like more details, please leave a comment.
