The Men's Patagonia Fitz Roy Trout Cap Cool Sun Long-Sleeve Shirt is a fishing shirt for summers spent on the boat or in the river. Designed to wick sweat away from the skin and dry fast, the 100% recycled polyester jersey fabric feels great against the body and maintains comfort through the heat of the day. Thumb holes provide plenty of coverage while casting, yet leaving hands free to work, and a zippered chest pocket easily secures a pair of nippers or lip balm.
