The military-inspired “Beach Master” from Papa Nui is a classic take on the Vietnam-era “Beach Ball” styles popular with US Navy personnel on the sands of Vung Tau, Chu Lai and China Beach. Made from 100% cotton herringbone twill, the design adopts a close fit and short brim visor, which is multi-stitched for sturdy, non-flop styling — a simple, easy-to-wear summer hat that rolls up to fit in your back pocket.
