I've use Bolle Coach Whip sunglasses that I got from Costco. They were about $80.00 CDN. They are wrap around and have polarized dark green lenses (polycarbonate I think). I am very happy with them with the slight exception that when I have my clear face shield down, the polarization creates some mild distorions, nothing critical, just annoying, a bit of a rainbow effect in certain light conditions.
