Abstract: A ventilated adjustable cap for wearing on a user's head, the cap having a crown and a perimeter band surrounding a circumferential edge of the crown. The perimeter band has a forehead offset, which projects from the remainder of the perimeter band such that the forehead offset generally does not contact the user's forehead. The forehead offset promotes evaporative cooling of the user's head by permitting ambient air to pass between the user's head and the ventilated adjustable cap. The cooling may be further aided by a perforated air passage at the front side of the crown and by one or more water-retentive members. The cap may further have a torsion spring, an elastic band, or both to span at least one edge gap in the circumferential edge of the crown, opposing widening of the edge gap in the direction of the circumferential edge and help to fit the cap snugly on the user's head.
