The Empire EVent ZN Thermal Goggle is built around the innovative Empire goggle and lens systems. With the Pro Player in mind, Empire has added replaceable, lightweight, foam ear-pieces, plus an Empire goggle strap and lens retainer. The E-VENT comes standard with a clear thermal dual-pane lens to have you ready for any conditions straight out of the box. Dual-material molded construction means that this system will go the distance without faceplate separation and will never compromise on your safety. The E-VENT Goggle is ultra-low-profile, ergonomically designed for maximum comfort, super lightweight, and best in class for optics and clarity. *NOTE: The dark lens pictured are not standard but are optional!
