The HighCom ACHHC (Advanced Combat Helmet High Cut) is HighCom's flagship ACH high-cut ballistic helmet, built from a hybridized Kevlar and UHMWPE Spectra fiber shell and independently tested at an NVLAP-accredited, NIJ-approved laboratory against NIJ Standard 0106.01 Level IIIA threat parameters and MIL-STD-662F fragmentation resistance requirements. It ships standard with the D3O TRUST Stealth 7 pad system and is available in sizes Small through XL, weighing between 1.7 lbs (S) and 2.0 lbs (XL). Multiple harness configurations are available, with a 4-point harness included as the standard fit.

Who this is for

• Law enforcement officers and security professionals who need certified handgun and fragmentation protection in a high-cut profile that keeps ear-mounted comms gear fully accessible.
• Military and government contractors requiring a helmet independently tested to NIJ 0106.01 and MIL-STD-662F frag standards with a serialized product trail and compliance documentation.
• Prepared civilians and range shooters who want a ballistic helmet with a documented test record, quality pad system, and a fit range that accommodates heads from 21.1 to 26 inches in circumference.

Threat rating and standard

The ACHHC is independently tested at an NVLAP-accredited, NIJ-approved laboratory to meet or exceed ballistic resistance as specified under NIJ Standard 0106.01 at Level IIIA. Covered threats include .357 Magnum 158 gr. Jacketed Soft Point at 1,395 fps, 9mm 124 gr. Full Metal Jacket Round Nose at 1,400 fps, and .44 Magnum 240 gr. Semi-Jacketed Hollow Point at 1,400 fps. Head protection zones cover the front, back, crown, and sides.

The ACHHC does not protect against rifle-caliber threats. No wearable ballistic helmet currently achieves rifle-round defeat at the Level IV equivalent — the ACHHC is rated for handgun and fragmentation threats only.

MIL-STD-662F fragmentation performance

Fragmentation resistance is independently tested to MIL-STD-662F. V50 results by fragment size are published in the table below.

Shell material and construction

The ACHHC shell combines hybridized Kevlar fiber and UHMWPE Spectra fiber in a single composite construction. This hybrid layup balances the high tensile strength of aramid fiber against the low areal density of UHMWPE to achieve Level IIIA protection across a weight range of 1.7 to 2.0 lbs depending on size. The high-cut geometry opens the ear area fully, making the helmet compatible with over-ear communication systems while maintaining front, crown, back, and side ballistic coverage.

Suspension and retention

Every ACHHC ships with the D3O TRUST Stealth 7 pad helmet system as standard. D3O's rate-sensitive polymer stiffens on impact to absorb and distribute energy, which addresses both comfort during extended wear and behind-helmet blunt trauma mitigation. The standard retention setup is a 4-point harness. Multiple alternative harness configurations are available — contact us if you need a specific harness setup confirmed before ordering.

Sizing

Head circumference is measured around the head at the widest point, similar to hat sizing, in inches. If a measurement falls on the dividing line between two sizes, select the larger size to maintain maximum ballistic coverage. Size-to-weight data is shown below.

Frequently asked questions

What does NIJ Standard 0106.01 Level IIIA mean for a helmet?

NIJ 0106.01 is the NIJ ballistic standard specific to ballistic helmets, separate from the body armor standard (0101.06). Level IIIA under 0106.01 covers handgun threats up to .44 Magnum. The ACHHC was independently tested at an NVLAP-accredited laboratory to meet or exceed those threat parameters, covering .357 Magnum JSP at 1,395 fps, 9mm FMJ RN at 1,400 fps, and .44 Magnum SJHP at 1,400 fps.

Will this helmet stop rifle rounds?

No. The ACHHC is rated for Level IIIA handgun threats and MIL-STD-662F fragmentation. No commercially available wearable ballistic helmet defeats rifle-caliber threats at a Level IV equivalent. If your threat profile includes rifle fire, body armor plates are the appropriate protection layer — a helmet alone is not designed or rated for that role.

How heavy is the ACHHC and is that manageable for extended wear?

It depends on your size. The ACHHC weighs 1.7 lbs in Small and 2.0 lbs in XL, with a weight tolerance of ±0.15 lbs. Those figures sit at the lighter end of the ACH category for a hybridized Kevlar/UHMWPE shell. The D3O TRUST Stealth 7 pad system also distributes load across the crown, which reduces pressure-point fatigue during prolonged use.

What size do I need and how do I measure?

Measure your head circumference at the widest point, the same way you would for a hat, and measure in inches. Match that measurement to the size chart: Small covers 21.1"–21.9", Medium 21.9"–22.7", Large 22.7"–24.0", and XL 24.0"–26.0". If your measurement falls on a size boundary, select the larger size to maintain maximum ballistic coverage.

Does the ACHHC accept NVG shrouds and rail accessories?

The product page lists compatible Wilcox shroud accessories — including the Wilcox L4 One-Hole, L4 WMS Modular (Universal), and L4 Three-Hole shrouds — as related products for the ACHHC. Contact us to confirm specific mount compatibility with your NVG or rail system before ordering.

Can this helmet be shipped to my state?

The ACHHC cannot be shipped to New York or Connecticut due to those states' body armor restrictions. Connecticut and New York residents who are active law enforcement officers or government emergency response personnel may be eligible — contact us for details. 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. This product is subject to U.S. export regulations and may only be purchased by lawful U.S. persons.
