Abstract: A helmet includes a helmet body, and a sweat-collecting strap extending between opposed ends along an interior of the helmet body. The sweat-collecting strap has a gutter between the opposed ends thereof. Each end of the sweat-collecting strap is mounted along one of the side portions of the helmet body. The sweat-collecting strap is displaceable with respect to the helmet body to bias the gutter against a forehead of the wearer above the eyes.

Abstract: A face shield for a hockey helmet, comprising a transparent visor portion, a bottom portion, right and left side portions, and a top portion extending upwardly and rearwardly from the top edge of the visor portion. The top portion comprises a top central transversal bar, right and left bars extending upwardly and rearwardly on the right and left sides from the top edge of the visor portion and a central projection between the right and left bars projecting upwardly and rearwardly from the top edge of the visor portion. The central bar and central projection define a transversal gap therebetween and the central bar, right and left bars and central projection define right and left hollow spaces therebetween. The transversal gap and right and left hollow spaces together define a central aeration aperture being sized to prevent a hockey stick blade or puck from impacting the wearer's face.

Abstract: A protective helmet including an outer shell, and a liner assembly received in the outer shell and connected to the outer shell, the liner assembly defining a front portion configured to overlay a front of a head of a wearer, a rear portion configured to overlay a rear of the head of the wearer, a top portion disposed above and out of contact with a top of the head of the wearer when the helmet is worn, and two opposed side portions each configured to overlay a respective side of the head of the wearer. Each of the front, rear, side and top portions includes at least one zone where the liner assembly includes a plurality of overlapping layers.

Abstract: A protective helmet having a liner assembly received in an outer shell and connected to the outer shell, with front, rear, side and top portions each including at least one zone where the liner assembly includes a plurality of overlapping layers, each of the layers being made from one of first, second, third and fourth materials, where the first material has a greater density and/or hardness than that of the second, third and fourth materials, the second material has a greater density and/or hardness than that of the third and fourth materials, and the third material has a greater density and/or hardness than that of the fourth material, and wherein the liner assembly includes one or more particular zones set forth in Table 3 or 4.
