Based on the original M65 FISHTAIL PARKA, it is a product made in a silhouette that is close to a circular reproduction. As it is the 4th version, it is a product that actively applies the feedback it has received so far, and it is an original fishtail such as a removable hood, vintage textured COTTON/NYLON textile fabric, a liner jacket designed to show a softer and more natural silhouette, and brass-colored metal subsidiary materials. They made better use of the elements of the parka. It is made of solid C/N fabric with a vintage texture, so that it can have the original feel. It has the advantage that it can be used in all seasons except summer. In the case of the existing original product, the original product is made asymmetrically by only serving as a lining. In the case of a hood that can be detached/attached from the neckline, it is designed to be used more conveniently, and a wire can be inserted to make it into the desired shape. Based on the original M65 FISHTAIL PARKA product, this product was completed after much research. It is a good product that can be used in various ways regardless of the season by detaching/removing the hood and inner skin.
