Good sunglasses.

Nice sunglasses for price but don't keep pollen and dust out from my hard contact eyes when windy in Spring. Jawbreaker model does a better job.

The best sunglasses I have ever owned

I purchased the Oakley Flak 2.0 XL sunglasses with the Prizm Trail lenses. I use them mainly for mountain biking and hiking in the woods. I needed a lens that lets in a lot of light with good eye protection. They are lightweight, stay in place and everything looks awesome through the lenses. The lens is ideal for forest use but not enough for direct sunlight, so I will likely purchase a darker lens for road biking.
