HJELM™
Extremely light, modular and comfortable Gen4 head protection
Introducing the HJELM™ 4th Generation Combat Helmet — the result of advanced materials science, modular engineering, and integrated electronics. Built to set new standards in protection, connectivity, and operational efficiency for the future soldier system.
Hjelm features & Technology
Advanced head protection
The HJELM™ Combat Helmet System combines lightweight design with advanced electronics integration and robust fragment protection. Tailored for adaptability, the system enhances mission optimization and situational awareness, all while offering unparalleled comfort and stability.
STRUCTURAL ARMOR
RIGID SHELL + ADAPTIVE SKULL-PLATE LINER
The outer shell provides robust ballistic and impact resistance, while the internal skull-plate liner adapts to the shape of the wearer’s head for optimal load distribution and comfort. Together, they form a synergistic system engineered to resist penetration, reduce blunt-force trauma, and maintain stability under stress.
- Ballistic Shell: High-strength composite construction delivers maximum protection against shrapnel, fragments, and direct impacts.
- Skull-Plate Liner: Conforming liner that molds to head contours, enhancing comfort, fit, and force dispersion.
- Structural Stability: Designed to maintain helmet integrity during multi-hit scenarios and reduce secondary deformation.
impact technology
Maximum Impact Protection, Minimal Weight
Koroyd delivers advanced impact protection through its unique tubular core, which crumples on impact to absorb energy and reduce force transfer to the head. Proven to lessen rotational motion by up to 91%, it outperforms traditional materials, making it ideal for high-performance and combat helmets.
- Impact Protection: Crumple-zone tubes absorb and control impact energy, reducing injury risk.
- Breath & Flow: Open-cell design releases heat and lets fresh air circulate.
- Ultralight to Go: Made of 95% air for lighter, thinner protection that reduces fatigue without compromising safety.
OPEN INTERFACE SYSTEM
SEAMLESS INTEGRATION AND MISSION FLEXIBILITY
HJELM™ features an open interface architecture that ensures full compatibility with new technologies and mission equipment — enhancing situational awareness in all conditions without compromising mobility or agility.
- Edgemount™: Lightweight attachment system allowing technical devices and accessories to connect securely without adding bulk.
- HASP™: Modular mounting solution designed for rapid configuration and integration of mission-specific gear.
- Mission-Ready Integration: Supports camouflage, sensors, and system components for seamless customization to meet any operational requirement
Evolution of the combat helmet
FROM GJERMUNDBU TO HJELM™
Uncover the stories behind our cutting-edge helmets, where every detail is a testament to our commitment to protection, innovation, and excellence.
In the summer of 1915, the large number of lethal head wounds that artillery inflicted upon the French Army led them to introduce the first modern steel helmets, closely followed by the first British combat helmet to be specifically designed and engineered for Western Front battlefield conditions. These helmets were in reality no different in construction than the metal helmets worn by Roman soldiers in ancient times and are considered the first generation of military helmet design.
Generation II was marked by the invention and adoption of Kevlar material bringing about improvement in both protection and weight. The composite material construction of aramid fiber and resin for the ballistic shell was very good at stopping high speed fragments as well as most caliber handgun bullets.
Wearing technology on the head for purposes other than protection started the third generation of military helmet evolution. In the early 21st century, use of communication headsets and night vision goggles became common place and required a new level of helmet integration with accessory components. The earliest versions of these third generation helmets incorporated night vision mounts and ballistic shells trimmed higher to provide clearance for headset earcups.
The NFM HJELM™ helmet line was developed to be the first Generation-IV ground infantry platform capable of integrating information technology while advancing protection from battlefield threats. The foundation for this system is an internal liner system that holds the helmet on the head comfortably and securely. It is coupled to a lightweight shell made from the highest grade of ballistic materials, and every gram of performance is optimized with state-of-the art processing techniques.
What makes HJELM™ a truly Generation-IV helmet is the Edgemount™ with Helmet Attachment System Pattern (HASP™). Unlike traditional rails and Velcro® which have limited attachment options and added material to the outside of the helmet, independent of devices being attached or not, the Edgemount with HASP means technology can be integrated only where it is needed.
