With the advent of military aircraft in WWI most of the early pilots soon discovered that appropriate protective headgear was a necessity due to the cold and the all too frequent occurrence of oil leaking into the slipstream and covering the pilot. Originally the German military was caught unprepared and no specific headgear or uniforms for pilots were available. This resulted in the pilots utilizing commercially produced motor car helmets. These tight fitting, soft leather helmets proved to be ideal and future flight helmets were basically modified versions of the early motor car helmets. During WWII the Luftwaffe utilized no fewer then ten slightly different models of flight helmets with the main modifications being helmets issued for summer or winter wear and helmets with or without integral radio communication fittings. The LKpW101 model helmet was designed for winter wear and was outfitted with radio equipment as used by fighter pilots and bomber commanders. The LKpW101 model helmet was basically identical to the earlier LKpW100 model but with improved communications equipment.
