Found this idea for low sun in winter This is the cheap version http://www.webbikeworld.com/Reviewed...roducts/shade/ This is the more expensive version http://www.super-visor.com/sunblocker.htm Looks a good idea. Does anyone know where get either in NZ? I where glasses that tint in UV light but visor on helmet blocks UV so glasses dont tint. This looks a good solution
