3M SecureFit 400 Series SF401AF Green/Black Temples, Clear Anti-Fog Lens

The 3M™ SecureFit™ SF401AF Protective Eyewear delivers a secure, self-adjusting fit engineered for all-day comfort in demanding work environments. At the core of its design is 3M™ Pressure Diffusion Temple Technology — slotted ribs built into the dual-injected temples that flex and equalize pressure, automatically conforming to the wearer's head size without manual adjustment. A soft one-piece nose bridge further enhances comfort during extended wear.

The clear anti-fog lens features both anti-scratch and anti-fog coatings, maintaining optical clarity in variable temperature and humidity conditions — essential for jewelers, metalsmiths, and bench technicians working in close proximity to heat sources, polishing equipment, and fine detail work. This eyewear meets ANSI Z87.1-2003 and CSA Z94.3-2007 safety standards. Made in the USA with globally sourced materials.
