The B3 bomber jacket shearling has a rich history that dates back to the 1930s and 1940s. Originally designed for pilots flying at high altitudes, the jacket was crafted to provide maximum warmth and durability. The shearling lining, made from sheepskin, offered insulation against freezing temperatures, while the rugged exterior protected against harsh winds. Today, the B3 bomber jacket shearling from NY American Jacket pays homage to this legacy, blending historical authenticity with contemporary design.
