I now own two pair of these glasses. i wear one cycling and the other in the car. i have also ordered a pair for a friend. these are one of the best bargains i have gotten in years. why pay 10x more for same thing? just for the name on them? i do not think so! i have felt like a sales rep for inbike while discussing eye wear with other cyclists, i have recommended them to dozens of people and i know some who have ordered some themselves. they are very durable and very comfortable. i have a problem with sunglasses making my head hurt, but that is no issue at all with these.
