This MA-1 style jacket is not sold in Japan. It's a single-layer design, making it a lightweight outer that's perfect for spring and autumn, like a windbreaker that blocks the wind. The olive color, reminiscent of military jackets, combined with the aluminum zipper gives it a vintage feel. I bought it about 10 years ago at Tanner Goods in Portland. - Brand: PENFIELD - Color: Olive - Size: S (Width 53 x Length 64 x Sleeve Length 88cm) - Design: MA-1 Style - Material: 100% Nylon
