Aviator Trapper Hats are a spin-off style of the hats bomber pilots wore in WWII. They feature a curved dome style top (which differs from the flat top of the Russian style hats). They also have extra long ear flaps, and a wide front brim. The fur trim aviator trapper hat is this season's hottest style. They make a great ski hat. Nothing beats it for style and functionality. Designed to be worn with the ear flaps down for warmth and style or neatly attach them at the top of the crown.
