The Shellback Tactical Level IIIA Ballistic High Cut ACH Helmet delivers NIJ 0106.01 Level IIIA ballistic protection, MIL-STD-662F fragmentation resistance, and impact protection in a high-cut shell built from hybridized Kevlar and UHMWPE Spectra fibers. The low-profile design reduces shell weight to as little as 2.6 lbs (Medium), opens access to communication equipment, and minimizes interference with target acquisition. Available in Medium, Large, and XL, this helmet is backed by a 5-year ballistic warranty and manufactured in the United States.

Who this is for

• SRT and SWAT operators who need certified handgun and fragmentation protection without sacrificing access to comms or optics
• Special operations and tactical teams requiring a high-cut profile that clears hearing protection, NVG mounts, and rail-mounted accessories
• First responders and prepared civilians looking for a NIJ-tested ballistic helmet with documented performance data at a price well below mil-spec tier options

Threat rating and standard

The helmet is rated to NIJ 0106.01 Level IIIA, defeating 9mm FMJ RN (124 gr at 1,400 fps), .357 Magnum JSP (158 gr at 1,395 fps), and .44 Magnum SJHP (240 gr at 1,400 fps). Back-face deformation on the 9mm test measures less than 25mm at 1,400 fps. All ballistic testing is completed by an NIJ-certified laboratory.

Fragmentation resistance is tested and documented to MIL-STD-662F. The helmet is not rated for rifle-caliber threats. No wearable helmet currently achieves Level IV or RF3 protection — this helmet protects against handgun rounds and fragmentation, not rifle fire.

Shell material and construction

The ballistic shell combines hybridized Kevlar aramid fiber and UHMWPE Spectra fiber in a high-cut ACH profile. The high-cut geometry keeps weight low — shell weight runs 2.6 lbs (Medium), 2.7 lbs (Large), and 2.9 lbs (XL) — while clearing the ears and temples for communication gear and hearing protection. Country of origin is the United States.

Suspension and retention

An adjustable 4-point retention harness secures the helmet to the head. The D3O Trust 7 comfort pad system provides interior cushioning and fit customization. D3O pads absorb impact energy through rate-sensitive molecular behavior, hardening on impact while remaining pliable during normal wear. Reviewers note the 3/4-inch pad set accommodates standard ear protection such as MSA Sordins when pads are adjusted, allowing independent ear pro use when the helmet is not deployed.

Mount compatibility

The high-cut design is built to clear communication equipment and accommodate accessories. Contact us for confirmation on specific NVG shroud patterns, ARC rail kits, or mount compatibility before ordering. Shellback Tactical offers a side rail kit, velcro loop kit, and ratchet retention system as separately purchased accessories for this helmet.

Sizing

Measure head circumference with a tape placed at the middle of the forehead and approximately 1/8 inch above the ear. If a measurement falls on the dividing line between sizes, select the larger size.

Frequently asked questions

Can this helmet be shipped to my state?

This helmet cannot be shipped to New York or Connecticut due to state body armor restrictions. It is subject to US export regulations. Under 18 U.S.C. § 931, anyone with a federal felony conviction for a crime of violence is prohibited from purchasing or possessing body armor.

What does NIJ 0106.01 Level IIIA mean?

NIJ 0106.01 is the NIJ standard governing ballistic helmets. Level IIIA is the highest handgun protection level in that standard, requiring the helmet to stop rounds including 9mm FMJ at 1,400 fps and .44 Magnum SJHP at 1,400 fps. It does not protect against rifle-caliber threats.

Will this helmet stop rifle rounds?

No. This helmet is rated to NIJ 0106.01 Level IIIA, which covers handgun threats and fragmentation. No currently available wearable ballistic helmet achieves Level IV or RF3 rifle protection. For rifle-rated fragmentation resistance, look to MIL-SPEC PASGT or ECH standards — and note that even those do not stop direct rifle fire.

How heavy is this helmet and will it be comfortable for extended wear?

Total weight runs 2.8 lbs (Medium), 2.9 lbs (Large), and 3.1 lbs (XL). The D3O Trust 7 pad system handles interior comfort. Verified buyers note the harness may benefit from an aftermarket upgrade for prolonged wear, and that the 3/4-inch pads fit MSA Sordins for combined use with hearing protection.

What size do I need and how do I measure?

Wrap a tape measure around your head at mid-forehead, about 1/8 inch above the ear. Match that circumference to the size chart: Medium covers 21.9–27.7 inches, Large covers 22.7–24 inches, and XL covers 24–26 inches. When your measurement falls on the border between two sizes, select the larger size. Contact us if you need help choosing between sizes.

What is the ballistic warranty on this helmet?

Yes, this helmet carries a 5-year ballistic warranty. The warranty applies when the helmet is used as intended and does not cover everyday wear and tear, modifications, alterations, or improper use.
