Inspired by one of North America's largest and most iconic species, Native Eyewear Griz XD9014 Polarized Sunglasses definitely subscribe to the maxim that bigger is better! Oversized, masculine frames sport large lenses with N3 polarized lenses for glare reduction, UV protection, superior contrast, and impact resistance. These ophthalmic-grade polycarbonate lenses deliver 100% UV protection, block more than 90% of potentially harmful blue light, and are finished with oleophobic and hydrophobic coatings that resist water, dust, dirt, oil, and fingerprints while preserving the appearance of the lens against wear and tear. Additionally, select styles have mirror coatings to help reduce glare even further. These frames are the largest in the Native Eyewear product line and are the first active piece they designed with side venting. The Rhyno-Tuff Air Frames on these Native sunglasses are made from eco-friendly material that is extremely lightweight, yet durable enough to withstand high-velocity collisions and temperature extremes. Cam action hinges lock into place. Cushinol nose pads and temple tips ensure a secure, comfortable fit, working in tandem with the Mastoid Temple Grip design to hug the area behind your ears and keep the sunglasses right where you need them. Like their namesake, you might find Native Griz sunglasses trailblazing in the Beartooth Mountains or patiently waiting along the river for their next lucky catch. All Native sunglasses come with a microbag and a mfrs. lifetime limited warranty. Manufacturer style #: XD9014.
