The Columbia Flyin Dry Booney is a multi-talented booney that keeps you protected from such assailants as coastal overspray, tropical downpours as well as unrelenting sun rays. As its name implies, the Columbia Flyin Dry Booney is built to keep you dry. Omni-Dry ultra-breathable waterproofing combines with full seam sealing to simultaneously block wet weather and encourage interior airflow. Omni-Wick EVAP uses cutting edge moisture management technology to disperse sweat, whisking it away so quickly that you are dry before you even feel the damp. A drawcord with a toggle at back of crown cinches to the perfect fit, and the adjustable chinstrap keeps things in place through powerful offshore gusts.
