The big, stylized Black Panther mask logo is printed off-center, taking up most of the lower left side of the shirt. The shiny jet black design is printed against the black cotton shirt, allowing you to both blend into the shadows and still catch the light when you move. This ThinkGeek exclusive design is the perfect shirt for prowling… only, you know, casually. 100% cotton. Machine wash cold, gentle cycle. Tumble dry low. Imported.
