Get excellent vision and durability even in extreme working conditions. We’ve extended the 3M™ SecureFit™ Protective Eyewear 400 Series by adding the premium 3M™ Scotchgard™ Anti-Fog coating as well an optional foam gasket.3M SecureFit Protective Eyewear 400 Series features soft adjustable nose pads, dual injected temples, and proprietary 3M Pressure Diffusion Temple Technology that helps diffuse pressure over the ear to enhance frame comfort while not compromising the security of fit across a diverse workforce. 3M SecureFit Protective Eyewear Series 400 naturally adjusts the temples to individual head sizes for a customized fit to each person. The durable, snug-fitting, flexible nature of SecureFit offers a more comfortable and personal fit than old-fashion one-size-fits-all glasses that are rigid and unyielding in design. The snug fit also helps keep the glasses securely in place as the wearer looks up and down or side to side, eliminating the need for frequent repositioning of the glasses due to head movement. Scotchgard Anti-Fog Coating gives superior anti-fog protection to ensure clear vision at all times. Removable Foam Gasket provides enhanced protection from debris. This protective eyewear weighs less than 20 grams for lightweight comfort. Effective in both hot and cold weather.
