Abstract: A sweat diverting gutter integrated into headwear for removing perspiration that escapes the material including a substantially u-shaped gutter formed from upper and lower gutter portions connected by at least one connecting post and a corresponding post receptacle between the gutter parts. The placement of the diverting gutter on the exterior side of the headwear causes excess sweat to be laterally moved from on or around the wearer's forehead away from the eyes and face.

Abstract: A head band device for protecting a wearer's eyes from perspiration from the wearer's forehead is provided. A substantially nonabsorbent band includes a front band portion and two side band portions. The gutter structure extends from an outer surface of the band. The gutter structure includes a gutter base and a gutter lip. The gutter structure in combination with the front band portion and at least part of the first and second side band portions forms a perspiration channel with a generally U-shaped cross-section. The gutter base has a first thickness at a central portion thereof. The gutter base has a second thickness at end portions thereof. The first thickness is greater than the second thickness. The gutter base slopes from the central portion downward toward the end portions thereof, transitioning from the first thickness to the second thickness. A closure system has two fasteners and an elastic loop member.
