I have a UVEX Wing RS and an "ordinary" Wing. They're both 4 or 5 years old (can't remember which is which). Does anyone know if there's a direct replacement for either of these? "Wing RS" seems to have been hijacked by the non-engined fraternity - [URL]http://outside.away.com/outside/gear/gear-blog/20050831.html[/URL] and the nearest motorcycle equivalents seem to be these monstrosities - [URL]http://www.motowebshop.com/en/shop/helmets/fullface_helmets/uvex_wing_rs_740[/URL]. Mine are the original black jobs with the double-glazed clear/legal tint vizors. Any ideas?
