I have a pair of Bolle glasses I use for cycling. They aren't cycling specific, but they are sporty, don't slide around and are comfortable. Were they cheap? No...but I have found I take much better care of "designer" sunglasses than I ever did cheap ones. I have 3 pairs of designer sunglasses (Bolle, Ray Ban and Maui Jim), all are polarized and well made; I haven't had to buy a pair in 5+ years.
