Ops-Core FAST SF High Cut Gen2 Helmet System

Ops-Core is one of our go-to options for helmet systems. The FAST SF Gen 2 offers a significant weight reduction over the Gen 1 by way of the Gen 2 FAST SF Shell, LockDown liner, and Head-Loc chin strap, while still providing 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.

Features

• Ballistic protection from 9mm rounds (1200f/s) with a shell weight of just 1.23 lbs/557 grams (Size L) the FAST SF offers the same level of ballistic protection as its predecessor but with a 10% reduction in overall system weight.
• LockDown Liner System incorporates a user-customizable suspension system with multiple strategically placed pads, encouraging airflow, and the moisture-wicking fabric and reticulated foam, offers adaptable density for diverse head shapes and comfortably supports heavy VAS and NVG systems.
• Conformable nape pad and cable Occ-Dial® offer enhanced stability, securing a larger contact area on the rear of the user's head, adapting to individual contours for an improved fit compared to other, more rigid systems.
• Redesigned Head-Loc Flex retention system introduces a unique convertible chin cup that can be worn either over or under the chin, eliminating the need for a mask extender with the 02 and CBRN kit for most users.
• PowerPath ARC Rail system provides a lightweight mounting solution for Ops-Core headborne systems and features a unique, behind the rail channel for the safe routing of NVG cables.
• Lightweight Modular Bungee Shroud (MBS) reduces snag hazards and features carabiner clips to improve NVG retention and stability while reducing interference with other rail-mounted accessories.
• External VELCRO loop kit allows for quick and easy attachment and detachment of headborne accessories.

Terminology

• 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.

Ballistic Testing

**Not all suspension/retention options are tested to full stated standards.

***9mm is V0 tested at this velocity with Backface Transient Deformation (BTD) under 23.4mm (Crown), 27.1mm (Sides), 29mm (Front), and 19.1mm (Rear) when tested on multi-sized clay-filled headforms in accordance with the USSOCOM FTHS Specification.
