What ballistic standard does the SS-401 Advanced Combat Helmet meet?
The SS-401 has been tested by an NIJ-accredited laboratory and found to meet or exceed ballistic resistance requirements specified under NIJ Standard 0106.01, the primary U.S. standard for ballistic helmets. The aramid composite shell with thermoset resin reinforcement surpasses the standard's minimum requirements, providing reliable protection against handgun-caliber threats consistent with Level IIIA performance expectations.
What is the D30 TRUST 7 pad system and why does it matter?
The D30 TRUST 7 is a seven-pad interior suspension system that maps geometrically to the human skull, maximizing deceleration during blunt impact. D30's rate-sensitive polymer material stiffens rapidly under impact to absorb and spread force across multiple cranial contact points, outperforming flat foam pads in independent blunt-impact acceleration tests. Pads attach via hook-and-loop for easy customization, cleaning, and replacement. The result is a helmet that exceeds competitor performance benchmarks at comparable weight.
Does the SS-401 fit with communications headsets and NVG mounts?
Yes. The SS-401's full-cut profile and Picatinny-style side rails are designed to accommodate tactical accessories including push-to-talk communication systems, helmet cameras, and NVG mounting hardware without permanent modification. The full-cut geometry provides ear clearance that is compatible with over-ear hearing protection and tactical headsets, making the helmet suitable for both armed and medical responders who require communications equipment in the field.
What sizes are available for the SS-401 helmet?
The SS-401 is available in four sizes: Small, Medium, Large, and Extra Large, with approximate head dimensions of 7.9–8.3" H × 6.3–6.5" W. The dial ratchet retention harness provides additional micro-adjustment within each size band, allowing a precise, one-hand-tightenable fit even while wearing gloves. Agencies ordering for entire shift rosters should measure personnel circumferentially at the widest part of the head (above the ears and brow) to select the appropriate size.
Is the SS-401 suitable for Rescue Task Force (RTF) personnel who are not sworn law enforcement?
Yes — the SS-401 was specifically designed with Rescue Task Force responders in mind, including EMS providers who deploy into the warm zone alongside law enforcement during active shooter and mass casualty events. Its full-cut design provides broader cranial coverage for medics who work at ground level. North American Rescue is a primary supplier of tactical medical equipment to U.S. military and federal law enforcement, and the SS-401 is available to qualifying civilian responder agencies.
Is the SS-401 helmet NIJ 0106.01 tested?
Yes. The SS-401 Advanced Combat Helmet is tested to NIJ Standard 0106.01 for ballistic protection. Verify the current NIJ certification documents with NAR before operational deployment to confirm the tested protection level.
What training is required to use the SS-401 helmet?
The SS-401 is personal protective equipment, not a medical device. Operationally, users should be trained in proper fit adjustment using the dial-ratchet harness and in NIJ ballistic protection level interpretation. RTF teams should train in donning/doffing under stress.
How does the full-cut SS-401 compare to high-cut helmets?
The full-cut design protects the temporal bones and occipital region that high-cut helmets leave exposed — critical for medical personnel working at ground level where lateral threats are more likely. High-cut helmets provide better hearing and communication device access; full-cut provides more coverage at the cost of some audio passthrough.
What is the NSN or procurement path for the SS-401 helmet?
Available through MED-TAC International. Agency procurement can leverage GSA Advantage or state/federal grant funding for personal protective equipment. Contact NAR or MED-TAC for current NSN and contract status.
What accessories are compatible with the SS-401 helmet?
The SS-401 includes Picatinny-style side rails for lights, cameras, and night-vision accessories. Verify accessory compatibility with NAR specifications for the current generation helmet; mounting hardware specifications are in the product data sheet.
