GU and UNDERCOVER collaboration MA-1 jacket, lightweight and stylish design. Thank you for viewing. - Brand: GU - Color: Khaki - Material: 66% Polyester, 34% Nylon Although it has no lining, the fabric is sturdy and warm. It looks like a light khaki depending on the light, but it's a darker khaki. I'm selling it because I only wore it last year and it's been in my closet. Please check the photos. The design is very cool.
