Headbands are stylish, functional, comfortable, cool... and cooling. Andre Agassi, Björn Borg, Ralph Macchio, Iverson... the list goes on and on.
A warning to the wise, however. There is a darkside when it comes to headband wearing. Take your Richie Tenenbaums and your Dirk Digglers. If you ever find yourself reliving your old tennis days with a razor in your hand, or think you're cocaine's gift to karate and pop music, it's time to take a step back, look in the mirror, and take that headband off.
