Weighing just over 8. 8 ounces and featuring 33 oversized vents with moisture evacuation channels, the Louis Garneau Quartz II Helmet offers ultra light, incredibly airy protection from nasty spills on the road. Its Super MSB technology places ring shaped plastic along the base of the helmet to reinforce its perimeter in the case of a heavy impact. The lightweight composite skeleton provides extra structural support upon impact. Further shielding your noggin from heavy blows, you'll find the helmet's In Mold construction fuses the polycarbonate outer shell to a foam liner for impact absorbing protection. X Static XT2 antimicrobial padding dries quickly and resists funky odor build up when you're sweating profusely. The Spiderlock Pro II closure system stabilizes the helmet without causing pressure points or uncomfortable bunching. Plus, it quickly tightens with the simple spin of a dial for easy on and off. As a bonus, you'll find included reflective decals for added safety when you're riding in low light conditions, such as dawn and dusk hours.
