Designed to trek incredibly lightly, this vented button-down is made of 100% recycled polyester—so it holds its own against snagged branches and brambles. Omni-Shade UPF 50 sun protection provides coverage when there isn't a cloud in the sky. For non-stop comfort, Omni-Wick technology wicks perspiration and helps this shirt dry quickly, plus antimicrobial treatment keeps it fresh mile after mile. Features you'll love include roll-up sleeves, dual chest pockets, and a classic shirttail hemline. Columbia offers this long sleeve shirt in multiple colors and sizes. Extended sizing available. Regular Fit.
