Built for those who push past the ordinary, the SPY Mainline ANSI RX Sunglasses bring an extra-large frame designed to handle just about anything you throw at it. Finished in Matte Sand, this bold, oversized frame offers a warmer, more neutral alternative to traditional black or gray frames, while still holding up across a wide range of settings—whether you’re out on the water, deep in the desert, or just navigating everyday life. It’s a frame built with versatility and durability in mind, made for people who want their gear to keep pace with an active, no-compromise lifestyle.
This pair features SPY’s Happy Gray lens technology, designed to enhance color and contrast while preserving natural, true-to-life color perception in bright, high-exposure environments like open water or sun-drenched landscapes. With a Cat. 3 lens rating, these sunglasses are built to perform well in strong daylight conditions. The frame is also notable for its ANSI RX Z87-2+ rating, meaning it’s rated to accommodate prescription lenses while still meeting recognized impact-protection standards—a valuable feature for anyone who needs corrective lenses but doesn’t want to give up on protective, performance-driven eyewear.
Beyond the lens and frame rating, the Mainline is built with a handful of additional technologies aimed at long-term durability and everyday comfort. An anti-fog coating helps keep vision clear during temperature shifts or high-output activity, while an anti-scratch coating helps the lenses hold up to regular wear and tear over time. The frame itself is constructed using eco-friendly materials and features a snap hinge for smooth, reliable function. Altogether, the Mainline ANSI RX is designed for those who want a rugged, prescription-ready pair of sunglasses that doesn’t cut corners on performance, comfort, or style.
