The Cobra P2 Modular Suspension System (MSS) is comprised of an impact liner, dial fit band, suspension and retention system. The impact liner is made of low profile impact material and exceeds U.S. Army ACH impact standard. An adjustable crown net allows for sweat wicking and comfort. It suspends the helmet shell on the wearer’s head, meaning the impact liner does not come into contact with the head, providing a free flow of air for cooling benefits. A dial fit band with comfort pads adjusts the fit around the circumference of the head using a dial ratchet mechanism that can be quickly tightened or loosened using one hand. The 4-point retention system has a height adjustable nape pad to ensure stability with NVG use.
