Outer Shroud for M-Series Helmets

The 3M M-446 outer shroud is a fabric cover designed for M-Series headgear. It fits the M-400 and M-407 Versaflo helmet models. The component serves as a replaceable outer layer for the helmet assembly. Supplied new, it integrates directly with the existing head protection system.

Compatibility and replacement use

This shroud suits users who need a replacement fabric cover for a compatible M-Series helmet. It is not intended for buyers who require a complete helmet assembly or a different protective system. Workers using headgear outside the M-400 or M-407 models will find this part incompatible. Those needing additional accessories beyond the outer shroud should seek other components.
