The Signature feature of the Velocity Series is the patented Orbital Seal that protects your eyes from the wind, glare and airborne irritants with a 100% complete enclosure. The perfect seal created by the removable eyecups keeps soothing moisture in while providing an effective barrier against wind and weather.
A speed rating of SR75 means Speed Series models are roughly 75% effective in blocking wind, dust peripheral glare and other environmental irritants. Properly fit, they can provide nearly the same protection as a Velocity Series model, and they deliver more performance and protection than ordinary sunglasses.
