The Smith Mainline Polarized Sliders provide crystal clear vision & maximum protection in sunny realms. Anytime you have a flat surface reflecting sunrays (e.g., snow, water, your windshield, even sand and pavement), a polarized lens is what you want protecting your eyes. The Mainline frame is made from durable Grilamid and hugs the curves of your face, giving a slight wrap-around look to minimize the effects of wind, snow, and glare. Its larger frame fits most people, but is ideal for medium to large faces. Smith sunglasses offer 100% protection against harmful UVA and UVB rays.

Mainline Sunglasses

Smith Mainline sunglasses are a very good solution to the high-power New Mexico summer sun and blinding glare. I now own two pairs. I am a big fan of these shades.

Slider Mainlines - Third times not the charm.

These are my third set of Smith Slider Mainlines. The first two pair gave up their life saving my vision. Once in a Mountain Biking accident the other when a line trimmer kicked up a rock hard enough to brake the frame. The only difference between this pair and the others is that I have only changed lenses four or five times and the lenses are already scratched, something that never happened with the previous pairs.
