Keep your temperature in check with the Columbia Coolhead™ Ball Cap. The Omni-Freeze™ ICE advanced cooling technology uses naturally occurring chemistry to start actively cooling down your head when the fabric comes into contact with sweat. When the process occurs the cap actually feels cool to touch. Also the flat-filament Omni-Wick™ fabric pulls moisture away from the skin to keep your head dry and fresh.
