Fred Perry Flat Cap in Black. A British icon in its own right, the flat cap is immensely eternal, with its roots dating back centuries; from farmers to working-class labourers, this accessory is favoured by many and rivalled by none. Made from a cotton/poly blend, the slick design comes in all black with a tonal version of Fred Perry's Laurel Wreath to the side and a colourful tartan lining.
