This full-face mask, along with a NATO CBRN rated filter (not included), is designed for military and law enforcement to protect against chemical, biological, radiological and nuclear threats. The stiff integral face piece is transparent and the structure is the actual supporting body of the SGE 400 protective mask. Its task is to replace the rubber bodies previously employed by traditional designs to bear the weight to which the mask is subjected. The main part of the face-piece, which consists of a large round surface in front of the eyes, is set back in the structure, thus keeping the overall dimensions to a minimum, reducing the risk of scratching and allowing the use of optical instruments so often used in today's armed forces. The unique design allows for a substantially reduced mask weight and a better field of vision (practically the whole mask is transparent). Protection of the face is guaranteed by the impact and cut resistant structure. Laboratory tests have been carried out proving that the polycarbonate body is left unharmed by a 6.35 caliber bullet hitting it at a speed of more than 150 m/seconds, providing full protection for the face and eyes against extremely violent impacts. FACE SEAL: Traditional masks consist basically of a load-bearing rubber structure fitted with two sealed eye-pieces, and since the rubber body has to bear the weight of all the accessories attached to the mask it has to be made rigid and thick (heavy and uncomfortable) and will therefore not adhere comfortably to the wearer's face. Our face-seal, on the other hand, is made of very soft rubber with a supple bellows type structure which allows perfect sealing and a very high degree of comfort even after very prolonged use. FILTER FITTINGS: The SGE masks have a threaded fitting for application of standard filters (DIN 3183, UNIEN 148-1). The shape of the internal ring nut allows perfect ventilation of the whole face-piece.
