The FiveStar Leather B-3 Flying Jacket is a faithful reproduction of the 1937 USAAF version, constructed with high-quality sheepskin and reinforced with heavy Russet Brown Horse Hides. The sheepskin is uncoated, while the fleece has a thickness of 20-22mm and is colored to match the original. The leather straps, made from durable cowhide, are secured with vintage Brass buckles in a Nickel finish for an authentic look. A buckle on the left chest keeps the collar in place and a chain hanger loop adds functionality. If you need help with sizing, please don't hesitate to contact us for expert advice.
