Redefining Protection Where It Matters Most.
NEW BENCHMARK IN BALLISTIC PROTECTION
Rethinking Helmet Standards to Save Lives
Although body armor is restricted to a 44mm backface deformation (BFD) under NIJ standards, ballistic helmets face far looser limits—just 25.4mm for 9mm threats. This gap in protection is critical.
The head makes up only 12% of the human body, yet accounts for 50% of battlefield fatalities. From 2000–2021, over 444,000 U.S. military personnel were diagnosed with traumatic brain injury (TBI).
Modern helmets are lighter, but often at the cost of protection. Greater deformation under impact can lead to behind armor blunt trauma (BABT), with real-world testing showing skull fractures even from non-penetrating rounds.
At Extremis Systems, we believe helmet standards must evolve. Our mission is to engineer next-generation combat helmets that minimize deformation and maximize survivability against projectiles, shrapnel, and IEDs.
Athena Helmet:
Transparent Data. Unmatched Efficiency.
The Athena is the only helmet on the market that publishes backface deformation (BFD) data across the full NIJ IIIA threat spectrum—setting a new benchmark for transparency and trust.
Powered by the latest in materials technology, Athena delivers unprecedented weight-efficiency while maintaining elite protection. In its weight class, it stands alone as the only helmet BFD-rated against all NIJ IIIA threats.
Proof in performance. Confidence in combat.
Standard features include:
2.75 fully dressed
360 modular suspension
Ratcheting dual-adjust retention
Ares Helmet:
Maximum Protection, Minimal Weight
The Ares Helmet combines the highest tensile strength carbon fiber with our proprietary composite technology to deliver unmatched lightweight performance.
Stopping 9mm threats with just 12mm of backface deformation—versus 29mm from leading competitors—the Ares sets a new standard in head protection.
Weighing only 2.15 pounds fully configured, it’s built for the missions where speed, agility, and survivability are non-negotiable.
Extreme performance. Zero compromise.
Standard Features
2.15 lb fully dressed
(L/XL high cut)
360° Modular Suspension
Ratcheting Dial-Adjust Retention
Tomahawk Helmet:
Built with the same advanced carbon fiber composite as our ultra-lightweight IIIA+ armor, the Tomahawk delivers superior protection without added weight.
While many competitors test only for penetration, the Tomahawk goes further—stopping threats with an average of just 22mm (0.87 in) of backface deformation, well below typical standards.
Engineered for impact. Trusted for performance.
Standard Features
2.8 lb Fully dressed (L/XL highcut)
360 Degree Pad System
Ratcheting Dial-Adjust Retention
Proven Protection Beyond Penetration
Introducing: the kuri cap
Kuri cap module
The Kuri Kap Module by Extremis Systems is a resilient field-tracking and situational awareness solution powered by Impatient Software's hardware and services.
