Shorty helmets are popular among cruisers because of their low profile style. The shorties we offer vary in strap, buckle, visor and shell construction and come in a very wide variety of colors, finishes and graphic designs. Most shorty helmet shells are made of a polycarbonate material to keep the cost down. Some helmet shells are made of fiberglass, stronger and a little lighter weight. The shorty helmet is now available in carbon fiber which is the lightest weight and strongest construction and of course the highest priced by two or three times the cost of the other helmet shells. You get what you pay for.
