The head band of a cap has a resilient member positioned around the rear of the cap with end portions of the resilient member secured to a frontal head band portion in the vicinity of the temples of the wearer of the cap. The end portions of the resilient member urge the frontal head band portion of the cap away from the forehead of the wearer and the frontal head band portion is formed in convex manner relative to the forehead of the wearer of the cap to provide a venturi-like opening between the frontal head band portion and the forehead for enhancing evaporation of perspiration from the forehead of the wearer of the cap.
