The ES125 Double Lens Mask is a low volume, low profile mask that provides an excellent range of vision. The split lens design allows the frame to sit low on the face, and is sealed by a soft, premium quality double seal silicone skirt. A high-impact plastic frame and tempered glass lenses will provide years of quality service. Adjustable mask strap buckles result in a more comfortable fit. Protective storage box included. The Double Lens Mask accommodates prescription and gauge reader lenses.
