Design
Because hard hats are intended to protect the wearer's head from impacts where heavy labor is being performed, they are made from durable materials, originally from metal, then fiberglass, and most-commonly (from the 1950s onward) rigid plastic.
Some contemporary cap-style hard hats feature a rolled edge that acts like a rain gutter to channel rainwater to the front, allowing it to drain off the bill, instead of letting the water run down the wearer's neck. A cowboy hard hat is a hard hat shaped like a wide rimmed cowboy hat, although some organizations disallow their use.
Organizations issuing hard hats often include their names and/or logos (or some other message) on the front of each hard hat.
