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.

combat uniform The FAST helmet ranges in weight from about 667–1592 g (1.47–3.51 lbs). The type of UHMWPE material for the ballistic FAST models provides increased protection against
NIJ Level IIIA handgun rounds. It can be fitted with a mounting bracket, patented first in 2014, for accessories like
night vision goggles and communications headsets, similar to
PASGT and
MICH. Users can wear it with different communications headsets with ease and comfort. The
Velcro featured on to the helmet also allows for the wearer to attach national flag or the emblem of unit which they belong to, in addition to other
IFF (Identification friend or foe) patches such as call sign and blood type. It has different color options, such as foliage green, black, olive green, ranger green, tan 499, urban grey,
MultiCam and desert
MARPAT. As well as having mesh and cloth
helmet covers in varying camouflage patterns. The FAST RF1 High Cut Helmet System released in 2021 is a rifle rated ballistic helmet at an average of 3.5 lbs (1592 grams) able to protect against
rifle rounds like the
7.62×39mm and
7.62x51mm due to the 0.400" (10.16mm) shell thickness. The different color options are tan 499, ranger green, MultiCam, black, and urban gray. The FAST XR Helmet System released in 2022 represents an intermediate in protection between the SF line of helmets and the RF1 Helmet System, protecting against 7.62×39mm rifle rounds at a distance of 10 feet, but not against larger rounds such as 7.62×51mm. This is due to having a shell thickness of 0.280" (7.112mm). It is far lighter than the RF1, averaging at only about half a pound heavier than the SF helmet, depending on the type of chinstrap. It is available in Tan 499, Ranger Green, MultiCam, Black, and Urban Gray. In addition to military and law enforcement, the non-ballistic version of the helmet also has gained considerable popularity among civilian occupations, such as outdoor sportsmen, journalists, disaster relief personnel and other field workers due to its modular design. ==Users==
