Perroz Designs already makes a number of helmet covers and they just introduced their newest for the Ops Core Maritime Helmet. The new cover utilizes 4 way stretch material in the central panel to achieve a trim, tight fit and accommodate a number of night vision mounting options. The side panels are constructed from 500D Cordura.
The cover may be removed without removing the night vision mounting plate. It features color matches loop Velcro fields on the sides and top/back. There is a 1/8th inch US GI MIL SPEC bungee cordage system over the top/back loop Velcro that can be used to help retain strobes and other mounted items.
