I think I posted it earlier, but I'm a big fan of Maui Jims and Oakleys.

I was on a trip to LA about 15 years ago and realized I had forgotten my sunglasses because I left home so early in the morning. I knew I had to get some because my eyes are very light-senstive, so I stopped at Sunglass Hut at LAX and for grins, tried on a pair of Maui Jim Kahunas. They felt like they were made especially for me. Since then MJs are the only sunglasses I bought for myself. The MJs I own (about 12 pairs) however are not suitable for cycling because of the glass lens.

I had bought a pair of Oakley Flak Jackets for my son back in the summer of '09, so when I started cycling again last winter, I borrowed his. I realized while riding that I didn't even realize I was wearing them because they felt so good. Unfortunately, I can't just buy one pair...I now have about 8 pairs (different color frames, different lens, different color ear socks, etc.) of the Flak Jackets. I'd probably like the Radars or Jawbones but I've been so pleased with the Flak Jackets (XLJs) that I'm sticking with them. An added advantage of the Flak Jackets is that they look normal enough to wear when I not riding (unlike the Jawbones).

I still have every pair of MJs I've ever bought...I rarely lose sunglasses.
