The Ops-Core Future Assault Shell Technology (FAST) Helmet, also known as the FAST helmet, is an American combat helmet used by special operations forces and law enforcement tactical organizations in various countries, as well as the current standard protective headgear of the Norwegian Armed Forces.
The FAST helmet series features a distinctive shell shape, with ear cut geometry which extends coverage over the rear occipital bone without load carrier interference, and optimizes weight distribution for increased stability, integration, balance, and comfort. The helmet features various suspension and retention systems, and ARC rails which, similar to picatinny rails, enable users to mount items like helmet lights and cameras.
