The Sheepskin B3 Bomber Pilot's Hat in solid Black leather with black wool. Famously used by pilots of the Second World War, these shearling hats are guaranteed to keep you warm in the coldest environments. This Aviator hat is made of double sided shearling with strong Napa leather on the outside to repel water and soft insulating wool on the inside. The ear flaps are designed to be worn down for added warmth, but they can also be secured up on the crown of the hat if the wool is too warm.
Natural shearling sheepskin is one of nature's warmest insulators. Breathable wool fibres are the perfect non-sweat material to keep you toasty and warm while maintaining dry comfort.
