If you buy Costa's it because you've never wore Maui Jim's
I've been through several pair of Coast's before finding out about Maui Jim's and now I'll never go back. The quality can't compare, Maui Jim's are on the leading edge of everything from the Featherlite weight frames to the crystal clear lens quality. My last pair of tgese were ran over by an 18 wheeler in a dirt parking lot and i was able to snap them back together the the only reason I have to buy a new pair is because I lost the last ones
