Spy Optic is one of a group of elite manufacturers to offer frames crafted in premium propionate. Frames constructed in propionate have a sleek, dense finish that is modern, comfortable, and durable. Some of our propionate frames are built with adjustable wire-core temples for a custom fit.
Epsylon™ is a comfortable composite plastic with a high tensile strength, allowing for the unique hidden hinge systems found in several of our fashion frames. Epsylon™ is lightweight and very resilient in a wide range of temperatures. Monel is an engineered alloy of three metals to create a lightweight yet extremely durable frame. Monel Alloy is both malleable and corrosion-resistant for well-fitting and long-wearing shades.
