The Hybrid Shroud was designed to allow the user to attach any of Wilcox's L4 Series line of NVG mounts onto a One-Hole or Three-Hole MICH/ACH helmet. 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. Lanyard Included.
