Combines high performance, customized fit, comfort and cost efficiency in a version of the reliable military-style gas mask (MCU-2/P) used by the U.S. Air Force in Operation Desert Storm. A flexible, one-piece polyurethane lens with a wide field of vision is bonded to the durable Hycar rubber facepiece. A drinking tube provides connection for fluid ingestion in contaminated atmospheres. An internal nose cup with two check valves deflects air from the lens and reduces fogging. A fully elastic, six-point head harness promotes easy on/off and adjustment, with no hair pulling. A standard mechanical speaking diaphragm is included, or MSA's optional ESP® II communications system can be added. A butyl-coated nylon hood is available for total head protection. The dual-canister mount allows weapon sighting from either shoulder. The CBRN canister contains chemical sorbents and a P100 filter to attract, retain and neutralize contaminants. The Millennium CBRN gas mask is designed to be used as a system, and while the thread and gasket meet the specifications of the standard, only MSA-manufactured components are tested and certified as assemblies.
