The Skullerz 8994 Anti-Scratch & Anti-Fog Hard Hat Face Shield is designed to increase eye and face protection for those using Skullerz Cap-Style Hard Hats or Safety Helmets. It protects against flying debris, splashes and particles and features a performance anti-fog and anti-scratch protective lens that will not wash or wear off over time. Fog-Off+ technology for scratch-resistance and enhanced permanent anti-fog performance won't wash off for clear viewing no matter the job, particularly useful for those working with dust masks or with extremely variable temperature. UV protection filters 99.9 percent of harmful UVA, UVB and UVC rays to keep eyes safe in the sun. The face shield is removable, and replacement shields are not included. It is tested to ANSI/ISEA Z87.1-2020 (Marks: Z87.1+) High-Velocity Impact Protection, anti-fog performance and optical requirements as well as CSA Z94.3.
