Far better than Oakley Gascan....
Where else can you find unisex sunglasses that looks great and works even for Mountain Biking and Beach Volleyball, my preferred sports. The SR-91 lens is far superior than Oakley, Ray Ban or Maui Jim. They rarely ever fog up and they tolerate all-day sun-filled drives perfectly.
I use them almost every day and the temple hinges are still tight as brand-new. I have the rare, discontinued gold model and they just get nothing but compliments from men and women alike.
