Keep the sun off your face and your sweat at bay by going old-school with a workout fave: the baseball cap. The easiest way to spice up an otherwise ho-hum outfit, these classically casual caps help you do away with crazy workout hair (you know you've been there) and add some personality to everything you do. Our favorites, hands-down, are Spiritual Gangster's rad snapbacks. Whether you consider yourself a spiritual gangster or workout warrior, you'll be sporting these around town long after your sweat sesh ends.
