A baseball cap is a soft, rounded hat with a stiff, protruding brim at the front, designed primarily for sun protection. It typically features a six-panel construction with a button at the crown where all panels meet. Most caps have ventilation eyelets on each panel, allowing air circulation to keep the head cool. The brim, often curved or flat, shields the eyes from bright sunlight, making it a favorite for outdoor activities. A key feature is the adjustable strap at the back—made of Velcro, plastic snaps, or a metal buckle—ensuring a snug fit for various head sizes. Baseball caps are usually made from cotton, polyester, or a blend of both, offering comfort and durability. They come in countless colors, logos, and designs, allowing for personal expression or team affiliation. Popular in sports, fashion, and casual wear, the baseball cap has become a global cultural icon. Its simple yet functional design continues to evolve while maintaining its timeless appeal.
