Crafted to provide a secure fit and strong protection, Ultra-Twin Full-Facepiece Respirators offer several options that make it a clear choice for defense against toxic chemicals. The unit features an inturned lip for a comfortable seal against the face, a large chin cup for easy positioning, and 5 suspension headstraps with roller buckles that hold the facepiece in place while minimizing hair entanglement. The wide lens is scratch resistant, while a speaking diaphragm provides clear short-range communications. The unit also features a nosecup that helps eliminate lens fogging.
