Learn how to properly fit and install the MTEK FLUX Helmet Cover Gen4 on your tactical helmet, with step-by-step instructions and sizing tips.

Quick answer

The MTEK FLUX Helmet Cover Gen4 is designed to fit the MTEK FLUX helmet precisely, but with careful attention to sizing and accessory routing, you can achieve a secure, rattle-free setup in under ten minutes.

Why fit matters for the Gen4 cover

A loose or misaligned helmet cover can snag on gear, shift during movement, or interfere with night vision and communications equipment. The Gen4 cover's semi-rigid rear flex cell and universal accessory management system only work correctly when the cover is fully seated and tensioned evenly.

The cover is available in multiple sizes to match the MTEK FLUX shell. Choosing the wrong size is the most common mistake—measure your helmet circumference before ordering.

Tools and preparation

You only need your MTEK FLUX helmet, the Gen4 cover, and a few minutes of uninterrupted time. No tools are required, but having good light helps you see the attachment points clearly.

Remove any existing accessories (NVG mounts, battery packs, counterweights) from the helmet before starting. This gives you full access to the cover's attachment loops and velcro panels.

How to fit the MTEK FLUX Helmet Cover Gen4

1. Orient the cover correctly: Hold the cover so the rear flex cell (the semi-rigid panel with cable exit holes) faces the back of the helmet. The front edge should align with the helmet's brow line. Common mistake: Installing the cover backward. Check that the cable exit holes point toward the rear of the helmet.
2. Seat the cover over the front brim: Stretch the front edge of the cover over the helmet's front brim, ensuring the material sits flush against the shell. Work your way around the sides, pulling the cover down evenly. Checkpoint: The cover should not bunch or wrinkle at the front. If it does, lift and reseat it before moving to the rear.
3. Secure the rear flex cell: Pull the rear flex cell over the back of the helmet. The semi-rigid panel should snap into place around the helmet's rear edge. Ensure the cable exit holes are unobstructed. Common mistake: Forcing the flex cell when it is twisted. Rotate the panel to align with the helmet contour before pressing it down.
4. Attach the velcro panels: Press the velcro panels on the sides and top of the cover firmly against the helmet. Start at the center and work outward to remove air pockets. Checkpoint: Run your fingers along the velcro seams. Any loose section will reduce the cover's stability.
5. Route cables through the exit holes: If you use an NVG battery pack or counterweight, feed the cables through the strategically placed exit holes in the rear flex cell before securing the accessory. Common mistake: Routing cables after the accessory is mounted, which can pinch or damage the wires. Always route first, then attach.
6. Final tension check: Gently tug on the cover at several points—front, sides, and rear. It should not shift more than a few millimeters. If it feels loose, remove and reseat the cover, ensuring all velcro is fully engaged. A correctly fitted cover will not rattle or shift during head movement. If it does, the size may be incorrect or the cover is not fully seated.
