A baseball jacket, also known as a varsity or letterman jacket, is a classic piece of outerwear initially worn by American high school and college athletes. Characterized by its wool body, contrasting leather or fabric sleeves, and ribbed cuffs, collar, and waistband, this jacket often features embroidered or chenille patches, representing school or team logos and achievements. Over time, it has become a fashion staple, appreciated for its timeless, sporty look that adds a casual, collegiate vibe to any outfit.
