The Spy Bravo Snow Goggles are a midsize goggle that features Lock Steady™ technology -- the quickest, fingerprint free lens change system on the market -- as your first line of defense against the ever-changing elements of Mother Nature. The Bravo is custom built from a flexible polyurethane frame and features a quick-change anti-fog 5.5-base ARC® spherical dual-lens system with anti-scratch protection, triple-layer Isotron™ face foam with moisture-wicking Dri-Force™ fleece, silicone-ribbed strap, and is helmet compatible with the most popular helmets on the planet. See better. Feel better. Perform better. Performance worthy of a standing ovation. This model comes with Happy Lens, SPY's color and contrast-enhancing lens with benefits.
