Which South Park boy usually wears a red-and-blue pom-pom hat?

The South Park boy who usually wears a red-and-blue pom-pom hat is Stan Marsh.

Stan’s signature outfit consists of a brown jacket, blue jeans, red gloves or mittens, and a blue knit cap with a red brim and decorative red pom-pom. His hat is one of the clearest visual identifiers separating him from his three closest friends: Kyle wears a green ushanka, Cartman wears a blue-and-yellow hat, and Kenny is usually enclosed in an orange parka hood.

Stan is one of South Park’s four central children, alongside Kyle Broflovski, Eric Cartman, and Kenny McCormick. He is voiced by co-creator Trey Parker and is loosely based on Parker himself. The character first appeared in the animated shorts The Spirit of Christmas before the television series premiered on Comedy Central in 1997.

Although Stan’s cap normally hides his hair, episodes occasionally show him without it, revealing shaggy black hair. His familiar clothing is part of the show’s deliberately simple cutout-inspired design: bold primary colors and limited angles make the children instantly recognizable even in crowded scenes.
