Ops-Core Fast SF Ballistic Helmet

The FAST SF Next Generation Helmet sets a new standard in high-cut ballistic protection. As the lightest FAST ballistic helmet ever produced, it integrates Ops-Core’s latest FAST SF ballistic shell, the LockDown™ Liner, and the Head-Loc® Flex chinstrap, reducing system weight by 10% compared to its predecessor.

Engineered for today’s most demanding missions, the FAST SF provides NIJ Level IIIA ballistic protection while weighing just 1.23 lbs. (Size L). Its LockDown Liner System delivers customizable suspension, moisture-wicking comfort, and enhanced stability, even under heavy NVG or VAS loads. The LockDown cable system integrates seamlessly with over-the-head comms headsets, while the convertible Head-Loc Flex chin cup allows wearers to adapt fit for O2 or CBRN mask compatibility without extenders.

With ARC PowerPath rails for accessory integration, a Modular Bungee Shroud for secure NVG retention, and tested resistance against extreme environments, the FAST SF delivers elite protection with unmatched comfort and modularity. Chosen as USSOCOM’s Family of Tactical Headborne Systems (FTHS), it represents the cutting edge of helmet design for modern operators.
