The mask is designed to give full support to the face by varying the thickness of silicone rubber and comes with its own protective case. The supplier of our new masks is a major rubber company having been in business since the 1950’s. They have patented the process of heat treating the silicone rubber where little or no fogging occurs. The frames are made from nylon material for superior strength. The plastic and silicone mold is of the highest quality and is evident when handling the mask. This mask has mirrored lens(hides your eyes and reduces glare while hunting).
