This is a New Era cap with a "B" logo, featuring a blue body and a black brim. The design is similar to the Boston Red Sox cap, but the blue and black color scheme seems to be a color variation different from the typical team colors. The tag indicates the size is "7 1/4" (57.7cm) and confirms it is "Genuine Merchandise" made of 100% wool. Please comment if you have any questions! Also, please follow!
