This kit is specifically for adapting our Helmet Scrims to the Canadian Issued CG634 legacy helmets. The kit includes two (2) side extensions and four (4) retaining tabs with shock cord. The side extensions are woven on the regular Helmet Scrim using the scrim’s perimeter shock cord. These simply add length and texture to the sides. The retention tabs can be added anywhere to the user likes and tucked into the suspension system.
