Serene in the face of serious heat and always up for a cleansing dunk in the hotel sink, an Island Hopper is traveler's manna. Its ultralight blend of moisturewicking 65 allrecycled polyester and 35 organic cotton ventilates well; the light colors reflect the sun, and the oversized dropin chest pockets sized for a fly box, passport or both have mesh vents to take in whatever breeze comes your way.
