Inspired by the hats bomber pilots wore in WWII, the aviator style hat is best known as a fur trim "ear flap hat". Aviator hats feature fur on the interior of the ear flaps and around the back of the neck. They also have a large fur flap brim on the front of the hat.
Aviator hats are unisex hats so they can be enjoyed by both men and women. The ear flaps can be worn down for warmth and style or attached at the back of the hat or top of the crown when not needed.
A special feature of the Aviator hat is that the main ear flaps have a secondary small fur ear flap located directly over the ear. These smaller ear flaps can be worn up or down. They serve two purposes. When worn down, they add extra warmth and protection to the ears. When worn up they allow for better hearing.
