The Men's Patagonia Tropic Comfort Natural Sun Crewneck is engineered from modal sun and spandex jersey. This material is supersoft, breathable, and durable, plus it delivers 40+ UPF sun protection. Designed for easy movement that wonÆt hinder the casting stroke, the longer sleeve length with thumb loops at the cuffs provides added sun protection for the backs of hands and a convenient hanging loop at the back makes hang drying simple. Made in a Fair Trade Certified factory, which means the people who made this product earned a premium for labor.
