Sailing? Same here, with Kenwood Cups and Big Boat Series in the past. In the end it was Melges 24s and I14s. I'm down now with injuries. Never used shades even in the hawaiian sun, because the salt and water drives me crazy. Of course 3 days into a sail up to America brought on the splitting headache from hell, so shades for the rest of the passage.
I have the Rudy Horus which has bendable nose and ear pieces. Very adjustable, not stylish, but good lenses.
The Livestrong Radar Path cost $190, but you know what Billy Cyrstal says in Fernando's Hideaway.
