RC 59FIFTY Navy, Size 7 1/2 Only tried on indoors The RC (Retro Crown) 59FIFTY is based on the 59FIFTY, but with a softer, lower crown for a classic fit silhouette. The interlining on the front panel is lightweight, gently maintaining the cap's shape. Although not a special model, it's made of wool material, not the current polyester material. *The sticker on the underside of the brim is peeling off.
