We've adapted our popular Super 64 low-profile tactical goggle to fit over prescription glasses. The Super 64 OTG (over the glass) offers the same level of ballistic protection and features as the standard model, but provides enough volume to fit other eyewear underneath the large, MIL-PRF 32431-A-rated lens and frame. With a thermoplastic rubber (TPR) gasket to keep airborne debris and other hazards out and our elite anti-fog technology (Vapor Shield), the Super 64 OTG was built to defend eyesight in the most hazardous environments.
