Brass Knuckle’s new lightweight Midnight Safety Glasses feature a face-tight gasket, SideShield, and wraparound protection for comfort. Lenses with BK-Anti-FOG protection help to keep vision clear in high-moisture, high-heat conditions. Each pair features a removable gasket made of ethylene-vinyl acetate foam, forming a dust filter that fills the gap between the glasses. When opened to wear, SideShield earpieces meet extended lenses at a tight, precision-cut seam for true wraparound protection. Each lens also offers 99.99% UV protection.
