Patagonia Men's L/S Cool Shade Shirt

At first glance, the Cool Shade looks like a classic, collared, button-front tropical travel shirt. Look a little closer, though, and you'll see it's a highly technical, fishing-specific piece of equipment for serious duty in high-sun environments. The all-recycled polyester/nylon yarn-dye blend provides 40-UPF sun protection and all-day comfort. The clean, modern styling features two zippered chest pockets sized to fit fly boxes, a breeze-catching vented back and roll-up sleeve tabs for easy function in heat and humidity. Put it all together and you have the ultimate workhorse for flats, blue-water or high-latitude summer fishing.
