A Letterman Jacket is a type of outerwear traditionally worn by high school and college students in the United States. It is typically made of wool with leather sleeves and features a large letter, often representing the student's school or athletic achievements, sewn onto the front. These jackets are commonly associated with sports teams, particularly in football, basketball, and track. Originally designed for athletes, Letterman jackets have evolved into a symbol of school pride and camaraderie. Students often customize their jackets with additional patches, pins, or embroidery to showcase their accomplishments, such as academic awards or participation in various clubs.
