Trucker hat

Instead of being made of cotton fabric like a typical baseball cap, the front section of a trucker hat above the bill is foam, and the rest is plastic mesh for breathability.

This design was intended to make the cap much cooler in the sun or hot weather for the comfort of the wearer.

[3] In the early 2000s, the trucker hat became a mainstream fashion trend, predominantly among suburban American youth associated with the hip-hop,[4] pop punk, and skater subcultures.

[5] This came about with a sense of irony due to the hat's rural or blue collar association and typically older demographic.

[6] It has frequently been donned by celebrities; musician Pharrell Williams and actor Ashton Kutcher in particular helped make the hat fashionable.
