 Versatile Protection in a Wide Range of Field Conditions

 The Combat IIIA Ballistic Helmet L110 helps protect against handgun bullets, blunt impacts, bomb fragmentation and select small arms projectiles, including 7.62 x  51 mm M80 NATO ball projectile with V0 @ 2100 ft/sec (640 m/sec) and V50 ballistic limit value >2460 fps (>750 m/s). The 3M combat II ballistic helmet L110  also provides fragmentation protection against 17 grain .22 cal FSP at >3,281 f/s (>1000 m/s) V50 when tested in accordance with STANAG 2920. The L110 is  resistant to penetration against NIJ IIIA threats.

 The versatile geometry of the helmet is similar to the U.S. Army Advanced Combat Helmet (ACH) and allows for the use of accessories, such as ballistic helmet  communications systems, eye, ear, and respiratory protection. The helmet also has a specially-engineered neck trim for providing enhanced coverage without  limiting movement when used in tandem with most ballistic vests.

 The combat IIIA ballistic helmet L110 uses an integrated retention system built from tubular nylon webbing which is reinforced with double bar-tacked stitching in  critical areas. In addition, it comes with an adjustable, smooth slide lock system and a padded strap for the nape of the neck which enhances stability for a secure  fit. The D30® Trust Helmet Pad System inside the helmet includes one circular crown pad, two trapezoidal pads, and four oblong pads which are designed to reduce  the force of blunt trauma while wicking away perspiration.



 Globally, military and police forces are seeking a state-of-the-art helmet to protect their service members from modern threats, like rifle fire and explosive devices.  The new Combat IIIA Ballistic Helmet L110 is designed to meet this pressing need at a level of comfort that appeals to users. The helmet leverages 3M scientific  expertise to deliver its highest ballistic protection to date and is based on a technology that has already been proven with the U.S. military.

 Designed for military combat operations and counterterrorism police missions, the Combat IIIA L110 helmet can help protect service members from bomb  fragmentations, certain rifle projectiles, handgun bullets, and blunt impacts. The helmet provides protection against select small arms projectiles including a V50  ballistic limit value greater than 2,400 feet per second (greater than 731 meters per second) against the 7.62 x 51 mm M80 NATO ball projectile.

 The Combat IIIA L110 helmet achieves its high level of protection without increased weight. This allows military and police forces to receive greater protection  without sacrificing mobility, which is required for today’s increasingly urban missions and close-quarters combat.

 The Combat IIIA L110 helmet is made with ultra-high-molecular-weight polyethylene composites and uses proprietary, seamless, ballistic-molding technology to  form a durable protective shell. The helmet’s proven geometry allows uninhibited movement when the helmet is worn with most ballistic vests with collars. The  helmet is offered in sizes small through extra-large and supports a variety of accessories and communication needs.
