Siege’s rugged detailing and full-rim rectangular frame shape incorporate additional side cup coverage to produce a look all its own. And since it’s made from incredibly tough yet resilient TR90 NZZ, you know these can take some punishment and come out unscathed. Gargoyles Siege lenses exceed the ANSI Z87.1 standards for high mass and high velocity impact protection as well as optical clarity. We also coat the lenses with anti-reflective and Tri Tech oleophobic treatments for reduced harsh light, smudge resistance and easier cleaning. The rubber temples and vented ribbed nose pad mean comfort isn’t an afterthought either. Protection, comfort and durability to take the world by storm with Gargoyles Siege sunglasses.
