Thanks to countless hours in Shoei’s in-house wind tunnel, Qwest owners will reap the benefits of exhilarating solitude on the road. A reduction of wind noise without blocking the road’s “informative sounds” was the ultimate goal, and that goal was achieved through optimal shell aerodynamics and liner components designed to prevent unwanted road noises from entering through the bottom of the helmet. The result: a staggering 2.2-decibel reduction in sound energy — 60 percent less than previous models! In addition to offering enhanced impact absorption by adjusting thickness and density in key areas, Shoei’s dual-layer EPS liner allows cooling air to travel unrestricted through tunnels created in the EPS, further augmenting the superior ventilation characteristics of the new Qwest.
