## Experience Classic Style and Ballistic Protection with Leupold Switchback Sunglasses The Leupold Switchback sunglasses give you classic styling and ballistic protection in a great looking pair of eyewear. The TR90-NZZ frame material is molded in a classic tortoise shell color. This frame is attractive and durable. Leupold's In-Fused polarized technology uses an advanced manufacturing process that fuses the polarization film between two of the lens layers. This process provides permanent polarized protection that won't scratch or deteriorate over time so you'll never have to worry about slowing down. All Leupold Performance Eyewear feature optically decentered lenses. Each lens is custom designed and machined to fit within its frame so that the clearest part of the lens is directly in front of your eye. The result is eyewear that eliminates distortion and maximizes clarity. Guard-ion is a hydrophobic lens coating that sheds dirt and water for a maintenance-free clear crisp image. Daylight Max provides UV protection for optimal performance in bright conditions. The Switchback gives you comfort style and ballistic protection for your everyday wear eye protection. ----------- ## Product Details - Frame Material: TR90-NZZ - Hinge Material: Stainless Steel - Polarized: Yes - Lens Material: Polycarbonate - UVA Protection: 100% - UVB Protection: 100% - Total Length (mm): 156 - Total Width (mm): 146.5 - Temple Length (mm): 116.2 - Total Height (mm): 47.8 - Lens Thickness (mm): 2
