3 seasons The liner can be removed, allowing it to be worn in spring and autumn. Size: M This is a replica of the extremely cold weather field jacket, which replaced the M51 parka from the late 1960s. It's a fishtail model with a longer back hem than the front, and a split tail like a tailcoat. It comes with a removable liner and can be worn for three seasons. The color and texture are well reproduced. Also, a removable hood is not included. I bought it from Nakata Shoten about a year ago. I've only worn it a few times, but the liner has a few scratches. There are also places where the cotton is coming out, but it can be removed by pulling it. It was sold as a set, but I don't think the liner and outer part attach to each other.
