Designed with Columbia's technical expertise is the Coolhead II Ball Cap that not only protects you from the sun, but also keeps you cool, dry and comfortable for longer hours in the greater outdoors. Full UVA and UVB -protective design, moisture-management system, and accelerated release of heat to provide coolness and next-to-skin-comfort is how we best describe the beauty of wearing this ball cap during any warm-weather activity. The sweatband is embedded with a sweat-activated super cooling technology that lowers the fabric temperature keeping you cool when the heat is on. A customizable hook and loop back adjustment allows the hat to fit comfortably on the head. This steady companion comes with a packable cape and will fit easily in any bag or backpack.
