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. This face shield 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. The shield features Fog-Off+ technology for durable scratch-resistance and enhanced permanent anti-fog performance that 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 sold separately. Integrated accessory slot allows Skullerz Earmuffs to be worn while face shield is in use. Safety glasses and headlamp can be worn while in use.
