Visor differences - black, iridium, mirrored?? Looking to get some visors for my helmet but apart from looking cool, are there any differences between visor coatings? I guess black is just darker but are the mirror and iridium versions just a coating or do they work differently and filter out more/less of the sunlight. Are they generally lighter than the black versions. Also what are the best ones for poor visibility - in snowboarding googles - yellow / orange were the best. I have a variety for my AGV already but have changed my helmet brand so looking to get new ones so interested in the differences. Thanks all simon |
