The Ultra-twin® respirator has an inturned lip around the edge for a secure, comfortable seal against the face. A large chin cup makes it easy to position, and the five suspension head straps with roller buckles hold the face piece in place while minimizing hair entanglement. The wide polycarbonate lens is coated to resist scratching and chemical attack. The mask comes with a speaking diaphragm for clear, short-range communications and a nosecup to reduce lens fogging in low temperature or high humidity conditions. The ultra-twin® mask has one set of attached, replaceable CS/CN (chlorobenzylidene/chloroacetophenone) riot gas filters. The masks are unused, as new with some storage marks.
