Whether you're biking, hiking, or running, you're bombarded by more than just UVAUVB rays. The Tifosi Saxon Sunglasses feature polycarbonate lenses that maximize protection and visibility in whatever scenario you find yourself. Both scratch resistant and shatterproof, these super construction lenses will not submit easily to bugs, rocks, or flying squirrels. Most sunglasses are manufactured with a thin polarized coating and labeled polarized. Tifosi, however, constructs its lenses with embedded polarized material that will never peel off. Weighing in less than an ounce, the TR 90 Grilamid frame is characterized by an extremely high bending strength, low density, and high resistance to chemical and UV damage. The nose and temple pads feature a no slip fit for confident movement during any activity.
