RUNS SMALL- is a size M but fits like a SMALL. Also needs to be “broken in”. (They gave me the wrong bag at the store that says small 🙃) The Defector leather jacket combines old school style with stand-out features, notably a forearm zipper, antique brass ball pull zippers, side straps, and a curved hem. The body features quilted lining and the sleeves are non-quilted. Fitted, premium leather relaxes and conforms to your shape and breaks in perfectly. Premium full grain buffalo napa leather is 1 – 2 mm thick. Leather and fit for style and function. Leather quickly conforms around your shape and breaks-in within one season. Ideal leather for motorcycle riding and built to last. 100% polyester, non-removable, quilted lining in the body and non-quilted sleeves. Ideal for comfort and weather. Double stitched seams in interior lining for additional reinforcement.
