Sr4 Swagger, Gun Metal Frame, Blue Diamo

The MCR Safety Swagger SR4 Safety Glasses in gun metal frame with blue diamond finish deliver professional-grade eye protection for automotive technicians, mechanics, and fabricators who demand both clarity and durability on the job. Whether you're performing engine diagnostics, welding repairs, or grinding metal surfaces, these glasses provide the optical performance and comfort needed for extended wear during demanding shop work. Designed for professionals who refuse to compromise between safety compliance and on-the-job style, the SR4 Swagger combines tactical aesthetics with ANSI-rated protection.

The Swagger SR4 features a lightweight dual-lens frame architecture that reduces fatigue during full-shift wear, critical when precision work demands sustained visual focus. Soft TPR (thermoplastic rubber) material is permanently bonded across the entire temple length and nose pad contact points, delivering secure positioning and comfortable grip even under sweat-inducing shop conditions or when wearing a welding helmet over top. The athletic bayonet temple design allows single-handed adjustment and maintains fit during active movement—essential when working in engine bays or underneath vehicles. This construction delivers the rigidity needed for impact resistance while the generous 4.05 x 3.1-inch lens footprint maximizes field of view for detecting potential hazards in tight mechanical spaces.

Mechanics working in high-heat environments, collision shops, and fabrication facilities benefit most from the SR4's proven durability and impact-rated lens construction. The compact 0.07 lb weight ensures they won't interfere with your work rhythm during lengthy transmission rebuilds, brake service, or suspension work. These glasses meet ANSI Z87.1 safety standards and work equally well over corrective lenses, making them ideal for technicians requiring vision correction. The gun metal and blue diamond color scheme resists showing grease stains common in automotive work, maintaining a professional appearance throughout your service day.
