BASE LEVEL HEAD COVERAGE

UNDERSTANDING COVERAGE. Traditional methods for determining the amount of protective coverage a helmet provides are based on calculating the exterior surface area of the helmet shell. This approach can be misleading when comparing different helmet shapes because a larger helmet surface area does not necessarily mean more head coverage area. We use standardized computer modeling techniques to project a line-of-sight “shadow” from the helmet onto the largest headform for a given helmet size. The surface area of this shadow is then measured to yield the true amount of the head that is actually protected, yielding an accurate representation of protective coverage.

HEARING PROTECTION & SITUATIONAL AWARENESS

The shape and edge trim of Ops-Core helmet shells is specifically designed to maintain natural hearing and sound localization during normal use. In high noise environments, the Ops-Core RAC-1 headset provides hearing protection without degrading situational awareness by using 3D Hearing Technology (3D HT) to restore a user’s ability to discern what direction sounds are coming from.

HEARING PROTECTION

  • Ear cushions ergonomically fit the head geometry, providing a better seal and increased noise attenuation
  • Un-tethered double-layer hearing protection provides noise attenuation in excess of typical active noise reduction (ANR) equipped headsets
  • Noise-cancelling microphone mounts to left or right ear cup

SITUATIONAL AWARENESS

  • By coupling a patented ear simulator design with binaural audio and advanced audio by processing, the RAC-1 Headset delivers hear-through audio that accurately preserves azimuth and elevation cues to provide situational awareness

FIT

WORM-DIAL

Ops-Core’s Worm-Dial liner system features an adjustable fitband with integrated chinstrap and repositionable multi-thickness impact pads. The fitband allows the user to properly adjust the liner around the perimeter of the head for a customized fit and optimal comfort. The length, width and overall shape can be set by simply turning the worm-dial. Together, these features ensure a correct and stable fit, per individual user, and enable the helmet to support the weight of the equipment and endure moment forces during demanding and lengthy military operations.

The liner system is also compatible with a variety of communication headsets and hearing protection devices, including headband style COMMs. For use with COMMs, the headband slides under the liner fitband and sits between the top impact pads, eliminating pressure points commonly experienced when wearing traditional liner systems. The impact pads are designed and pre-molded to the shape of the head. The materials used in pad construction are not affected by temperature, moisture or altitude.

LUX LINER

The Ops-Core Lux Liner is a revolutionary suspension system that combines a one-piece full coverage impact layer with modular, breathable comfort pads that can be customized and repositioned for comfort without affecting impact performance.

The Lux Liner retrofits the Ops-Core FAST Ballistic High Cut and Maritime Helmets and is available in two variations: with a low profile Worm-Dial fitband, or with Ops-Core H-Nape Head-Loc chinstrap. Both systems utilize the same impact layer. The liner is easy to install into FAST helmets using the existing Velcro pattern in the shells and comes in S/M, M/L, and L/XL sizes.

STABILITY

RETENTION SYSTEMS

The patented Ops-Core Head-Loc Retention System has a unique strap geometry that creates straight force lines to evenly distribute the helmet load on the head. This design gets rid of any slack in the straps that causes instability and slipping problems in all other conventional chinstraps, which can be detrimental to the mission at hand.

The Ops-Core system utilizes Head-Loc Sliders that provide on-the-fly, one handed adjustment and eliminate loose ends, while keeping the chinstrap low profile, lightweight and snag free. This adjustment is especially important when wearing NVGs or conducting rigorous physical activities. Tightening the chinstrap stabilizes the helmet without the need for counterweights or other bulky devices, facilitating a high performance head-borne platform. All of these features combined result in a retention solution that is secure, comfortable and adaptable to a variety of mission scenarios and environmental conditions.

 

HEAD-LOC CHINSTRAPS ARE 3X MORE RESISTANT TO ROTATIONAL FORCES THAN STANDARD ISSUE CHINSTRAPS

 

 

MATERIAL DESIGN

Helmets are worn for extensive periods of time under extreme environmental conditions; therefore the materials selected for helmet components must be able to withstand substantial amounts of wear and tear while also providing consistent protection, comfort and support. These requirements can be contradictory and difficult to achieve and often require innovative solutions with unique combinations of materials and parts.

Ops-Core uses different materials carefully designed and selected to work with one another to provide the desired performance benefits. The highlighted components represent just a few of the many ways we are working to improve the comfort, weight and capability of our 2014 products.
