The New FAST SF is Ops-Core’s lightest weight ballistic helmet system yet. This weight reduction is enabled by the introduction of three new subsystems: the next-generation FAST SF ballistic shell, the LockDownTM Liner, and the Head-Loc® Flex chinstrap. Features Ballistic protection from 9mm rounds (1200 f/s) with a shell weight of just 1.23 lbs/557 g (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, enouraging airflow. The LockDown Comfort Liner, featuring moisture-wicking fabric and reticulated foam, offers adaptable density for diverse head shapes and comfortably supports heavy VAS and NVG systems. LockDown 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. LockDown cable system enables an interference-free fit with headband communication 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 O2 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 thesafe 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® Brand loop kit allows for quick and easy attachment and detachment of headborne accessories.
