Beautiful pre owned jacket. Medium weight nylon/pol blend with pigskin letter striping down both sleeve and leather embellishments on the front lettering. This is an excellent jacket to break the wind without feeling bulky. I preferred this over my leather jacket while my knees were in the breeze! I have never had a jacket receive mor compliments than this one. Zippered venting at chest front and back. 2 outer pockets, 2 inside pockets. Sexy and slimming. Size Small but fits more like a medium.
