Shoei Inertia GT-Air Street Bike Racing Motorcycle Helmet - TC-2/Medium The all-new CW-1 shield is both wider and taller than the CX-IV that it replaces. In addition, the CW-1 shield protects SHOEI riders from 99% of the sun's damaging UVA and UVB rays, and the three-dimensional injection-molding process ensures distortion free vision. Another advantage of the CW-1 shield is its ability to work in conjunction with SHOEI's optional Pinlock system to deliver fog-free vision in even the most challenging conditions. The new CW-1 Pinlock lens is larger, and offers fog-free viewing to the very top of the helmet's larger eye port. DOT approved. Meets the FMVSS 218 Standard.
