3M Peltor SecureFit 400 Safety Glasses - Clear Polycarbonate

The 3M Peltor SF400PC8 Sport SecureFit 400 safety glasses deliver professional-grade eye protection with a self-adjusting temple design that eliminates pressure points during extended wear. These wraparound safety glasses feature impact-resistant polycarbonate lenses that meet ANSI Z87.1+ standards for high-impact applications.

What Makes This Different

The patented 3M Pressure Diffusion Temple Technology automatically adjusts to different head sizes without manual adjustment, providing consistent comfort across varied facial structures. Unlike traditional safety glasses with fixed temple pressure, the SecureFit 400 distributes weight evenly across the temporal area. The wraparound lens design offers 180-degree peripheral protection while maintaining optical clarity across the entire field of vision.

Key Features

• Self-adjusting temples with Pressure Diffusion Technology for universal fit
• ANSI Z87.1+ certified polycarbonate lenses resist impact up to 150 ft/sec
• Wraparound design provides complete peripheral eye protection
• Anti-fog coating maintains clear vision in temperature transitions
• Lightweight 0.9 oz construction reduces fatigue during extended use
• Compatible with most hard hats and hearing protection devices
• Scratch-resistant lens coating extends operational lifespan

The clear polycarbonate lenses transmit 92% of available light while filtering harmful UV radiation up to 400nm wavelength. These safety glasses perform reliably in industrial environments, shooting sports, and tactical training scenarios where debris and projectiles pose eye injury risks. The flexible temple design maintains secure positioning during rapid head movements without causing discomfort or slippage.
