The Columbia Silver Ridge Long-Sleeve Shirt is designed to keep you dry, protected, and comfortable during long, active days in the sun. Ultra-tough 100% polyester Silver Ridge stretch ripstop fabric is bolstered with Omni-Wick technology, which pulls moisture away from the body to allow for quick evaporation. Built-in Omni-Shade UPF 40 sun protection shields your skin against harmful UV rays. A mesh-lined vent in back offers increased ventilation to keep you cool in the heat, while high-stretch side panels allow greater freedom of movement. The sleeves roll up and secure at the side tabs for versatile wear options. The Silver Ridge Long-Sleeve Shirt features a flip-up sun collar, buttoned front placket, sun protection cuffs, and hidden chest pockets with secure flap closures.
