Ballistic Helmet Types Explained: PASGT, MICH & FAST
Quick answer: PASGT, MICH, and FAST are three NIJ Level IIIA ballistic helmet designs that trade coverage for modularity. PASGT offers maximum protection but no rails; MICH adds side rails and NVG shroud; FAST prioritizes ARC rail real estate for accessories. All stop .357 SIG and .44 Magnum rounds.
Here are the helmets Bulletproof Zone carries that map to the profiles above. All are rated NIJ Listed under 0101.06 at Level IIIA, tested to stop .357 SIG FMJ FN and .44 Magnum SJHP rounds at up to 1,450 ft/s.
Protection Group Denmark Arch Level IIIA Ballistic Helmet
High-cut shell with full ARC rail coverage. The polyurea paint coating resists rain, oil, and impacts; the manufacturer reports reduced backface deformation of up to 50% versus baseline IIIA shells. Dial-fit retention system. Weight: 2.53 lbs (1.15 kg) without accessories.
Good fit for: buyers who need high-cut ARC rail compatibility with weather-resistant finish and dial-fit convenience.
Legacy PASGT Level IIIA Ballistic Helmet
Multi-layer aramid and ballistic polyethylene shell. Foam-cushioned leather headband. Includes base attachment for optional face guard. Weight: 2.9 lbs.
Good fit for: buyers who want maximum coverage, don't need rail mounting, and are working with a tighter budget.
Legacy MICH Level IIIA Ballistic Helmet
Fixed side rails for shroud accessories; front Wilcox NVG shroud. Higher ear cut than PASGT with increased coverage at the rear. Standard for law enforcement and SWAT applications.
Good fit for: LE and security professionals who need NVG integration and reliable ear/temple coverage without going full high-cut.
Legacy FAST Level IIIA Ballistic Helmet
High ear cut with wide ARC side rails and front NVG shroud. More rear and ear coverage than the PGD ARCH. Light shell with good performance-to-weight characteristics.
Good fit for: users running large over-ear comms headsets or needing maximum ARC rail real estate for cameras and lights.
Chase Tactical Lightweight Non-Ballistic Bump Helmet
No ballistic rating. Protects against blunt impacts only. Accessory rails for lights, NVGs, cameras, and headsets. Adjustable 4-point harness with padded suspension. Approximately 24 oz.
Good fit for: search and rescue, cave rescue, high-mobility tactical work where the threat environment does not include firearms.
Frequently Asked Questions
What is the difference between PASGT, MICH, and FAST helmets?
PASGT offers the most coverage but no built-in accessory mounting and can shift over your eyes when prone. MICH adds side rails and an NVG shroud at the cost of about 8% less coverage than PASGT. FAST cuts the ear coverage entirely and provides the most ARC rail real estate for communications and camera mounting. Each successive design trades coverage area for modularity and situational awareness.
What NIJ rating do most ballistic helmets have?
Most civilian and law enforcement helmets are rated NIJ Listed under 0101.06 at Level IIIA. This covers .357 SIG FMJ FN and .44 Magnum SJHP rounds. Level III and IV ratings apply to body armor plates, not helmets, because the weight required to stop rifle rounds at the head is not practically wearable.
Can civilians legally buy ballistic helmets?
Yes, in most US states. Federal law does not restrict civilian purchase of ballistic helmets, unlike body armor (which has restrictions under 18 U.S.C. § 931 for violent-felony offenders). Current-issue military helmets like the ECH are a different matter; those are controlled and not reliably available for civilian purchase.
What is a bump helmet and does it stop bullets?
A bump helmet is a non-ballistic helmet designed to protect against blunt impacts from falls, debris, and collisions. It carries no NIJ rating and will not stop a bullet or meaningful fragmentation. It is appropriate for search and rescue, climbing, caving, and similar environments where the threat is physical impact, not gunfire.
What is the lightest ballistic helmet available?
UHMWPE-shell high-cut helmets like the FAST variants are the lightest in the IIIA-rated category, typically running 2.2 to 2.8 lbs depending on size. Aramid-shell PASGT-style helmets tend to run heavier at 3 to 4 lbs. The weight difference becomes significant over a full operational day.
Do I need a high-cut or low-cut ballistic helmet?
If you're running over-ear communications headsets, a high-cut (FAST-style) is the practical choice; low-cut and mid-cut shells physically interfere with headset positioning. If you're not running comms gear and want maximum head coverage, a PASGT or MICH gives you more protection area. Get your head measured before ordering. See our ballistic helmet sizing guide for the measurement process.
Are ballistic helmets effective against knife attacks or blunt weapons?
Yes, meaningfully so. Ballistic helmets are tested for both ballistic penetration and backface deformation (the force transferred through the shell on impact). The same aramid and UHMWPE construction that stops bullets also absorbs energy from baton strikes, thrown objects, and edged weapons making contact with the shell. This is one reason corrections and law enforcement personnel find them useful in environments where firearms are uncommon but impact weapons are not.
Key takeaways:
- PASGT gives the most coverage but the least modularity. MICH/ACH adds rail mounting at modest coverage cost. FAST cuts the ears for full comms headset clearance and maximum ARC rail space.
- Most civilian helmets are rated NIJ Listed under 0101.06 at Level IIIA. No production helmet is practically rated for rifle threats.
- Shell material matters: aramid (Kevlar) is the proven standard; UHMWPE (Dyneema) is lighter at equivalent protection but costs more.
- Bump helmets share the same shell architecture and rail systems as FAST helmets but carry zero ballistic rating. Know which threat you're buying for.
- Fit determines protection. A shell that shifts on your head during movement is not protecting what it should be. Measure before you order.
