With a durable Hycar rubber facepiece based on a design developed for the U.S. Armed Forces, this clean, simplified respirator is up to 40% lighter than conventional full-face respirators and provides high performance, a customized fit, comfort, economy, and user acceptance. A flexible, one-piece polyurethane lens with wide field of vision is bonded to the facepiece, which also offers a standard nosecup that helps eliminate lens fogging. A standard mechanical speaking diaphragm is included or MSA’s optional ESP II communications system can be added. The fully elastic, six-point head harness promotes easy on-off and easy adjustment with no air pulling. The dual-canister, bayonet mount allows weapon sighting from either shoulder.
