Abstract

A forwardly longitudinally extending cyclist's protective helmet includes a dome shaped outer shell having a forward portion, a rearward portion, and a medial portion over which air flows substantially smoothly as the cyclist moves forwardly. That medial portion includes an upper crown and laterally spaced left and right sides extending downwardly and laterally from the crown. At least one opening is located in the medial portion, the opening facing rearwardly and bounded by elongated outer and inner edges which extend substantially laterally. Air flowing over the medial portion acts to aspirate air from within the helmet interior and outwardly through the opening.
