Abstract: The invention is a kit including a helmet having front straps fixed at a first end to the helmet such that in use, the two front straps fasten together. A continuous front strap is formed running from one fixing device to another, under the chin of the wearer and crossing the temporal line on each side of the wearer's face. Each front strap includes a magnetic or magnetically attractable element extending both above and below the temporal line when the helmet is worn with the front straps fastened together. The kit includes eyewear which extends on both sides of the face, along the respective temporal lines up to at least the points where the front straps intersect their respective temporal lines, and magnetically couples the eyewear to the magnetic or magnetically attractable element fixed to the front straps of the helmet.

Abstract: The present invention is directed to a self-adjusting retention system for a helmet including a front head belt, a rear basket and a tensioning means or device for tensioning the front head belt and the rear basket along a wearer's head. The tensioning means includes a spring and a cable attached to the front head belt. The spring tensions the front head belt via the cable. In addition, the present invention is directed to a helmet including a dome and a self-adjusting retention system attached to the dome.
