The HGU-84 helicopter helmet was developed by Gentex for the U.S. Navy and Marine Corps. Its rigid Graphlon® composite shell is pressure-molded laminated graphite and ballistic nylon. It is a lightweight, low profile, compact design. The HGU-84’s frontal opening is cut back for maximum peripheral vision. Its genuine sheepskin edgeroll covers a soft foam core around the entire edge of the shell. The lightweight, tapered earcups, cushioned earseals, and spacer pads provide excellent sound attenuation.
A half-inch thick styrofoam energy-absorbing liner provides impact protection and a preformed Super Comfort Liner assures a comfortable, stable fit. Its unique one-piece integrated chin-and-nape strap is threaded through the helmet and adjusts to provide a snug, stable fit.
HGU-84 helmets are available with your choice of HGU-55 style single bungee visor, dual bungee visor, single visor assembly, dual visor assembly, or with a dual visor assembly with an ANVIS quick disconnect. Standard color is white.
