191116: A variety of headgear made of straps and pads eventually turned in leather caps. The flat top helmet (shown here) was really more of a flimsy soft leather cap with earflaps to protect the ears. The earflaps had holes so the player could hear. The so-called "Bee-Hive" and "Dog-Ear" caps were also used during this time and closely resembled aviator hats. However, the flimsy leather shell did little to protect the head from jarring impacts.
