100% leather. Has 4 exterior pockets, 1 interior pocket. In GREAT CONDITION. I cannot stress enough the quality of this leather. Had this jacket for years and over time the leather has gotten softer and softer like a baseball glove. No signs of wear or tear. Leather is not too heavy nor light. I’ve moved on to another style which is why I am selling this jacket but it was one of my favorites for a long period of time. It’s so versatile- you can practically wear it all year long.
