FAST Helmet also known as the FAST helmet, is a combat helmet used by special operations forces and law enforcement organizations.The FAST helmet series is characteristic for its shell shape – ear cut geometry which extends critical coverage over the rear occipital bone without load carrier interference, and optimizes weight distribution for increased stability, integration, balance, and improved comfort. Compared to standard combat helmets, the FAST helmet offers up to 25% weight reduction and is notable for its early use of ultra-high-molecular-weight polyethylene fibers (UHMWPE) in its design.
