In the winter, this fur-lined leather helmet would have been worn with goggles to keep a flyer's face, ears, neck, and eyes from freezing.

First World War aircrew in open cockpits battled both the elements and the enemy. High altitude winter flying was a brutal affair and even brief exposure to the frigid air could cause severe frostbite. At the same time, pilots were wary about clothing that could interfere with vision and head movement during an engagement with enemy aircraft.
