I wear a pair of Gatorz Wraptor Rx sunglasses. Best I've ever purchased, even better than my most excellent pre-Luxotica take-over Oakley's. The Gatorz fit under a helmet easily, are really durable (made from light weight aluminum) and fit close to the face and come with a lifetime guarantee. If you're in the market for a new pair of sunglasses, give these a close look. BTW, they are really popular in the special operator community.
These are very competitively priced sunglasses made in America and are direct to consumer so you save a lot of money over a less than comparable pair from your eyeglass shop. Oh, and you can get replacement lenses for a fairly modest price if they get badly scratched from a fall.
