The FR-Tech® Quilted Hard Hat Liner – Long Neck with Detachable Mouthpiece delivers advanced thermal protection, flame resistance, and all-day comfort for workers performing high-risk tasks in cold weather. Built using premium FR-Tech® fabric, this liner combines the durability of nylon with the breathability and comfort of cotton—ideal for extended wear in demanding industrial conditions.

Rated to Arc Flash PPE Category 4 (ATPV 40 cal/cm²) and certified to leading North American flame-resistant standards, this liner provides essential protection for workers in environments such as electrical substations, switchgear rooms, utilities, high-voltage maintenance, oil & gas facilities, and industrial plants.

A soft modacrylic-viscose insulated interior and FR cotton lining provide lasting warmth, moisture control, and next-to-skin comfort. A built-in moisture barrier blocks rain, snow, and wind, allowing workers to stay warm and dry in severe weather. All seams are sewn with inherently flame-resistant thread, ensuring long-term performance with no compromise in safety.

The long neck design delivers full coverage of the head, ears, face, and upper neck, while the detachable FR mouthpiece offers additional thermal protection when conditions demand it. Hook-and-loop closures and universal helmet straps allow for fast, secure attachment to virtually any hard hat.
