The system is also able to mount to an ECH helmet using the One-Hole configuration. This uniquely designed shroud is manufactured from lightweight aerospace grade metals and polymers. A rubber gripping pad mounted between the shroud and helmet provides stability and vibration deadening in both One-Hole and Three-Hole configurations.
