The Head-Loc Retention System was developed to improve safety, comfort and stability of chinstraps used in MICH/ACH ballistic helmets. Every component, down to each stitch pattern, was designed specifically for this purpose, giving the ACH greater utility than ever before. Custom adjustment tabs allow the helmet to be adjusted while wearing it, without any hanging loose ends. Simplified strap geometry makes the system 3X more stable than existing chinstraps. The H-Nape is designed to provide more stability for heavier night vision devices such as binoculars and goggles. It features a wider nape pad, allowing it to better distribute the greater weight. The design creates straight lines from each attachment/cross point, making this chin strap system the most comfortable and stable on the market.
