The Shellback Tactical Level IIIA Ballistic High-Cut SF ACH Helmet delivers NIJ 0106.01 Level IIIA ballistic protection in a high-cut shell constructed from hybridized Kevlar and UHMWPE Spectra ballistic fibers. Manufactured in the United States, this helmet is built for military, law enforcement, and first responder applications where ballistic coverage must coexist with communications gear and night vision integration. The D3O Trust 7 pad system and Airlink Prime ratcheting harness make it wearable through extended operations, and shell weights start at 2.5 lbs for the Small. Available in Small, Medium, Large, and XLarge.

Who this is for

• Military and law enforcement personnel who require certified ballistic coverage without sacrificing NVG or comms integration in an operational environment
• First responders and tactical teams who need a high-cut shell geometry that keeps ears clear for hearing protection and communications headsets
• Civilian preparedness buyers who want a USA-manufactured, warrantied ballistic helmet with documented test data and modular accessory rails

Threat rating and standard

The SF ACH Helmet carries NIJ 0106.01 Level IIIA ballistic protection, the highest handgun-rated designation under that standard. All ballistic testing is completed by an NIJ-certified laboratory. The helmet stops 9mm FMJ at 1,400 fps, .357 Magnum JSP at 1,395 fps, and .44 Magnum SJHP at 1,400 fps, with 9mm back-face deformation held below 25mm. Fragmentation resistance is tested to MIL-STD-662F methodology against RCC and FSP projectiles from 2 to 64 grains.

This helmet does not protect against rifle-caliber threats. No wearable ballistic helmet currently achieves RF3 or Level IV rifle protection at a wearable weight.

Shell material and construction

The ballistic shell combines Kevlar and UHMWPE Spectra fibers in a hybridized layup that keeps shell weight to 2.5 lbs (Small) through 2.9 lbs (XLarge). The high-cut geometry opens the ear area for unobstructed comms and hearing protection, while loop Velcro panels on the exterior accept patches and accessory covers. The shell ships with ARC-style side rails and accepts the Wilcox or Unity 3-hole NVG shroud mount pattern.

Suspension and retention

The Airlink Prime ratcheting harness provides tool-free circumference adjustment for a consistent, repeatable fit under load. The D3O Trust 7 comfort pad system lines the interior, distributing contact pressure and managing impact energy. Total system weight — shell plus pads and harness — runs from 3.0 lbs (Small) to 3.4 lbs (XLarge).

Mount compatibility

The NVG shroud accepts Wilcox and Unity 3-hole mount patterns, covering the most common night vision mounting hardware in military and law enforcement use. ARC-style side rails are included and accept standard rail-mount lights, cameras, and communications accessories. Loop Velcro on the exterior shell provides additional attachment surface for sensors, IR patches, and identification panels.

Sizing

Measure head circumference with a flexible tape at mid-forehead, approximately 1/8 inch above the ear. If your measurement falls on a size boundary, select the larger size.

Frequently asked questions

Can this helmet be shipped to my state?

It depends on your state. Body armor cannot be shipped to New York or Connecticut due to state restrictions. 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. Contact us if you have questions about your state's restrictions before ordering.

What does NIJ 0106.01 Level IIIA mean?

NIJ 0106.01 is the ballistic standard specifically written for ballistic helmets, parallel to the better-known 0101.06 body armor standard. Level IIIA under 0106.01 covers high-velocity handgun threats including 9mm FMJ at 1,400 fps and .44 Magnum SJHP at 1,400 fps. All testing on this helmet was conducted at an NIJ-certified laboratory.

Will this helmet stop rifle rounds?

No. This helmet is rated to Level IIIA, which covers handgun threats and fragmentation. No wearable ballistic helmet currently achieves rifle-rated Level IV protection. The SF ACH Helmet significantly reduces risk from handgun rounds and fragmentation but does not provide protection against rifle-caliber ammunition.

How do I measure for the correct size?

Wrap a flexible measuring tape around your head at mid-forehead, approximately 1/8 inch above the ear. Match your circumference to the size chart above. If your measurement lands exactly on a boundary between two sizes, select the larger size. Contact us if you are between sizes and want a fit recommendation.

Does this helmet accept NVG mounts and ARC rail accessories?

Yes. The helmet ships with a Wilcox or Unity 3-hole NVG shroud and ARC-style side rails already installed. These accept the most common night vision and rail-mount accessories used in military and law enforcement applications, including lights, cameras, and communications gear.

What is the ballistic warranty on this helmet?

Yes, this helmet carries a 5-year ballistic warranty. The warranty applies to normal intended use and does not cover everyday wear and tear, modifications, alterations, or improper use. Contact us to initiate a warranty claim.
