Ops-Core helmet systems are one of our go-to options when we want ballistic protection, reliability in performance, and comfort all in one package. The FAST SF High-Cut weighs in under three pounds and offers protection against fragmentation, blunt impacts, and level IIIA pistol threats. The Ops-Core aftermarket eco-system is also very robust, allowing end-users plenty of options for mounting ear pro, lights, strobes, helmet covers, and everything in between. The FAST SF comes with an assortment of pads to help fit the helmet precisely to your head, including a nape pad that can help stabilize the helmet even more, giving you maximum comfort.

  • NIJ 0106.01 with NIJ 0108.01 Level IIIA (9mm FMJ @ 1,400 ft/s) Threat
  • FAST tactical ballistic helmet with a super high cut shell made of a hybrid composite of the most advanced Carbon, Unidirectional Polyethylene, and woven Aramid.
  • A high-performance evolution of the Ops-Core FAST MT Super High Cut Helmet, with an 8% weight reduction, while maintaining compatibility with FAST head-borne accessories.
  • Super high-cut ballistic helmet shell geometry extends critical coverage over the rear occipital bone without load carrier interference and optimizes weight distribution for increased stability, integration, balance, and comfort.
  • Ear cut geometry is 16mm higher than the FAST XP High Cut shell shape, allowing for clearance of larger communication headsets.
  • Super High Cut Skeleton Rails offer a lower profile with a 30% weight reduction from FAST MT Super High Cut Rails.
  • Features a lightweight Modular Bungee Shroud (MBS) which reduces snag hazards and interference. Carabiner clips improve NVG retention and stability.
  • Molded liner features a proprietary recessed groove, accommodating over-the-head communications headsets with no interference or user discomfort and the ability to doff and don without removing the headset.
  • Vented Lux Liner features an expanded polypropylene (EPP) liner, offering enhanced impact protection, and molded-in vent holes are integrated with the shell to provide increased airflow and reduce heat stress.

  • Obliquity: Deviation from parallelism or perpendicularity or the amount of such deviation. In our context, without using ten-dollar words, this is the angle at which an object strikes the helmet.
  • RCC: Right Circular Cylinder. These are cylinders of varying weights that are used in fragmentation testing.
  • FSP: Fragment Simulation Projectiles. Extremely similar to the RCC, but FSPs feature a chisel-shaped nose.
  • V0 or V50: A ballistic test where the helmet is placed over a clay-filled head form that, for helmets, usually includes a sequence of five ballistic impacts, one each to the front, rear, left, and right sides, and the helmet crown. V0 is the velocity at which zero projectiles penetrate the armor, and V50 is the velocity at which 50% of the projectiles penetrate the armor. These tests are usually performed at 0° obliquity with some tolerance on either side to provide some room for error.
