Zeal Optics Blast Sunglasses- Black

The oversized Zeal Optics Blast Sunglasses- Black provide 100 percent UV protection and feature a replaceable, removable sweatguard and adjustable silicon socks for a customizable fit. They also feature Zeal Optics' patented P.A.S.V. (Passive Air-flow System Ventilation) anti-fog frame, which allows cooler air from the outside to enter the front frame vents while pulling the warmer, moist air from the inside of the lens out through the side and top of the lens. The inner air space is continuously refreshed, virtually eliminating fog issues. They're best for medium to large profiles.
