The Only Shades I Need

I’ve used this style for close to 5 years. It fits perfectly on my face. Matches my style and the colors are excellent. I like the turtle shell and black.

Sharp lookin' shades!

My students said they looked "tough" and asked me where I got them from (I teach high school). Quality shades for the price, and even for more than the price. They're good looking and durable. Good fit for wider faces. Love em!

Great Lens

The fit is great!

The lens is great!

Thought the whole frame was black but found it to be two toned. I get a light reflection from the bottom of the frame. However,

I would still buy the same pair again because the fit a nd lens are superb!
