摘要： A high performance sport safety helmet. The helmet is formed by an outer shell adapted for fitting upon a wearer's head, with a frontal periphery defining a centrally arched portion forming a front opening exposing the face and a major portion of the forehead of the wearer. The shell further has a base periphery defining an arcuate base opening for receiving the wearer's neck. A flexible resilient expandable front band is secured to and extends across the front opening of the shell with a substantial portion of the band lying below the centrally arched portion. The band snugly engages and substantially completely covers the forehead of the wearer. An articulated shell liner is secured to and covers the inner surface of the shell. The liner is partially separable and non-detachable from the shell. A visor is pivotally secured to the shell and nestable between the shell and the shell liner for selectively shielding the front opening of the shell.
