Comments about Gargoyles Eyewear Gargoyles Alfa Sunglasses:
The sunglasses are great. I do suggest that the Sports Authority website specify that these sunglasses have polarized lens, and the color is smoke, because these sunglasses come in 3 varieties, not all polarized, and the website does not specify which one you are ordering.
