protective composite headgear bearing distinctive embedded marking , such as alphanumeric data , color patterns , or stylized designs . a patterned sheet is formed into headgear shape , and the patterned side is covered with solidifiable plastic composition . the outer layer of the resulting composite headgear is translucent , and the inner layer preferably opaque , so that the pattern between layers is protected from abrasion damage while readily visible to an onlooker . distortion of the pattern by the shaping of the original flat sheet is counteracted by pre - distorting the sheet oppositely to offset it .
