The body design of the 24 Series goggles provides a wide, unobstructed field of vision and can be worn with most half-mask respirators. The transparent protective PVC body permits a comfortable fit over prescription eyewear. The 2400F is a dielectric goggle and features a soft foam lining which cushions the face and improves the seal. The flexible elastic head band is adjustable which allows it to fit most individuals comfortably. This goggle is designed with indirect ventilation which allows for air flow while greatly reducing the occurrence of splash from entering the goggle. Choose the best safety goggles, choose MCR Safety!
