While you're chillin' outside soaking in rays on a relaxed summer day while one of your friends fires up the barbecue and the other makes sure the cooler's well stocked, your Native Eyewear Polarized Chilkat Sunglasses are hard at work blocking glare and protecting your eyes. These savvy aviators are as at home on your face on casual summer days as they are during more adventurous outdoor excursions, and no matter how casual you go, the Chilkats never waver in providing high tech eye protection, glare reduction, and a comfortable, stay put fit. The Chilkat's advanced N3 polarized lenses selectively block out specific parts of the light spectrum and eliminate glare to provide a crystal clear view with increased contrasts and optimal depth perception, while offering top notch protection against both infrared and UV rays. The Rhyno Tuff Air frame, made of a high performance thermoplastic, is super lightweight and as rugged as its name implies: it's made to withstand high velocity collisions and temperature extremes. So you won't have to panic if you accidentally drop the sunglasses on the ground, or if you're out in blazing hot sun or sub zero temperatures. The Chilkat's frame is shaped to provide comfortable, stay put grip, while special, non slip nose pads ensure the sunglasses stay securely in place. Native Eyewear includes a semi rigid case and a soft pouch along with the sunglasses so you can keep them in good shape once they're off your face.
