Smaller and more portable than a tree, but nearly as effective.
If there's not a big tree or a wide porch in sight, you can still escape from the heat of the day when you slip on the Patagonia Men's Cool Shade Long-Sleeve Shirt. This lightweight fishing- and travel-specific shirt offers serious protection from the sun, while back vents allow cooling breezes to circulate and roll-up sleeve tabs give you additional ventilation options. Two zippered chest utility pockets that are sized to fit fly boxes or other essentials round out the technical details on the Cool Shade. When the sun goes down and the stars come out, it also serves perfectly well as a casual-dress shirt for dinner at the lodge.
