FEATURES & SPECIFICATIONS
- Ballistic protection from 9mm rounds (1200 ft/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. 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 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® Brand loop kit allows for quick and easy attachment and detachment of headborne accessories.
