Onward Kashiyama 23区 lab. Size: 38 Color: Khaki Green, Olive The collar and the back of the jacket are made of melton wool, while the front, sleeves, and the hem of the back are down-filled. The sleeves are removable with a zipper, allowing for 2-way use as a vest. It's warm, not heavy, and looks great. Although it's a size 38, it's an oversized fit, and I feel it can be worn by those who usually wear L to 2L sizes. I purchased this from a wonderful person here. Thank you to the previous seller. I really like the design and functionality, but it was too big for me, so I'm putting it up for sale during the season. It's in excellent condition with little wear, but please refrain from purchasing if you are sensitive to used items.
