3M SecureFit™ Protective Eyewear SF410AS, Indoor/Outdoor Mirror Lens, 20 EA/Case

3M’s innovative temple design features slotted ribs that provide comfortable pressure equalization, allowing the temples to flex and self-adjust to the size of the wearer’s head.

Cuved temples apply pressure to the less sensitive back of the head, instead of the temples, achieving a comfortable fit even during rapid head movement.
