Product Description The Leupold Switchback Performance Sunglasses deliver a powerful combination of rugged durability and all-day comfort for the serious outdoor enthusiast. Built around a sleek matte black frame crafted from lightweight TR90-NZZ material, these wrap-style sunglasses provide full-coverage protection and a bold, modern aesthetic. The blue mirror polycarbonate lenses are engineered with Leupold&';s In-Fused polarized technology, which permanently fuses the polarization film between lens layers to eliminate glare without compromising optical clarity. Optically decentered lens construction ensures each lens is custom-machined to its frame, placing the clearest optics directly in front of your eye for distortion-free vision. Additional coatings include DiamondCoat scratch resistance and Guard-ion hydrophobic protection to shed water and debris. Soft-touch rubber bridge pads and stepped temples keep the frame firmly and comfortably in place through even the most demanding activities. ANSI Z87.1 rated and built from ballistic-rated materials, the Switchback is as tough as it is stylish.
