SCHOTT B3 SHEEPSKIN JACKETFrom the US Air Force, B 17 and B 24 bomber aircrafts were unpressurized so the unheated cabins got awfully cold at high altitude. This is why this B 3 sheepskin bomber jacket was invented: it kept the air crews warm during their perilous missions during WWII. The LC1259 allows for high isolation, you can count on it for the coldest winter days. Its old looking leather gives it a vintage and authentic dimension. 100% sheepskin leather Leather welted
