Give your helmet a proper fit

The FMA General Suspension System is a foam-pad liner setup for FAST-style airsoft helmets, replacing a basic strap liner with multi-point support. Pads sit at the forehead, rear, top and sides so the helmet’s weight is spread evenly rather than pressing on a few points.

Dial it in and lock it

A knob-type adjuster lets you twist to set your headspace, then locks so the fit holds through movement. That solves the common problem of a helmet strap working loose after a period of wear, keeping the shell steady all game.

Comfort that lasts

The breathable, strong foam inner cushions pressure points and helps manage heat, so the helmet stays comfortable across a long day at a Kent airsoft site or on exercise.

Steady under load

Because the support is spread across multiple points, the system helps stabilise the helmet when you add weight up top such as lights, action cameras or NVG mounts. A smart, low-cost way to refresh a tired helmet or upgrade a new build. Explore more head protection and rig parts in our tactical gear range.

Frequently asked questions

Which helmets does this fit?

It is designed for FAST-style tactical helmets that use standard suspension fixed points. Check your helmet has matching mounting holes before fitting.

What does the knob adjuster do?

The knob-type adjuster lets you twist to tighten or loosen the headspace, then locks so the fit does not loosen while you move.

Will this make my helmet more comfortable?

Yes. The multi-point foam pads spread the load across the forehead, rear, top and sides, which is more comfortable and stable than a basic strap liner.

Is this a replacement for a worn liner?

It works both as a replacement for a tired or damaged liner and as an upgrade to a more supportive suspension setup.

Does it help when running mounted kit?

The stable multi-point support helps steady the helmet when you have lights, cameras or NVG mounts adding weight up top.
