This is a Ralph Lauren RLX Golf down jacket. It's a versatile navy color with a cool and stylish logo. The size is XS (165/88A), but I believe it's equivalent to a Japanese S to M size. It's only been used for two rounds of golf and is in clean condition. I think you can use it for purposes other than golf as well. Size details: XS, Length 66cm, Shoulder width 44cm, Body width 52cm, Sleeve length 64cm
