MTEK Flux Ballistic

Impact Liner/Retention Size:

Advanced Undercut Geometry. Multiple Protection Levels. All under 2.2lbs (1kg)



The FLUX Ballistic is the cornerstone of the innovative FLUX helmet system. This helmet was specifically designed to give you the highest level of safety, comfort and modularity currently available in a modern ballistic helmet. The lightweight shell is constructed of high performance polyethylene fibers, and features an undercutting geometric profile that follows the natural shape of your head providing exceptional stability and coverage. Additionally, all of the removeable fasteners have been designed for maximum strength and weight savings in order to further reduce the total system weight. 

The FLUX Ballistic features a 100% boltless shell. There are zero cuts or holes in or through the ballistic material, assuring maximum ballistic performance. The high cut edge profile was designed to be compatible with a wide range of existing communications headsets and accessories. Lightweight polymer retaining structures are bonded to the outside of the FLUX shell and provide a secure mounting platform for the FLUX M-LOK accessory rails and the Wilcox L4 three hole shroud. Several variations of ballistic side covers and mandible will soon be available to increase the protective coverage of your helmet if needed.

The interior Fluxliner™ offers excellent impact protection and is manufactured using a proprietary rate-sensitive foam. Two sets of adjustable comfort pads are included with each helmet, which let you manage the internal layout to customize the interior just for your head. The retention system also features Cam-Loc sliders for ease of adjustment, an ultra-suede chin cup. The ends of the retention terminates with Inverseclips® allowing for easy removal and additional safety.
