A trucker hat, also known as a mesh cap or netback cap, is a type of baseball cap. It originated in the early 1970s as a promotional giveaway from U.S. feed or farming supply companies to farmers, truck drivers, or other rural workers. The design of a trucker cap is similar to that of a baseball cap, with a slightly curved bill in front, a cap constructed from six almost triangular gores, and a button on top. However, 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. The foam front of the hat stands up straight and stiff, which makes the trucker hat taller than most baseball caps. The key features of a trucker hat include the breathable mesh and the snapback closure for adjustable sizing. Trucker hats are often associated with a more casual and laid-back style. They are popular for outdoor activities like hiking, camping, or working in the sun due to their mesh back panels, which provide excellent ventilation, and foam front panels that offer protection against the elements, such as wind and light rain. In the early 2000s, the trucker hat became a mainstream fashion trend, predominantly among suburban American youth associated with the hip-hop, pop punk, and skater subcultures. Today, trucker hats come in many colors, slogans, prints, and embroidery, and they are unisex, making them a favorite accessory across all genders.
