The OCCUNOMIX SX700 is a shoulder-length winter hard hat liner designed for cold-weather jobsite use. Built with a 3-layer construction, it fits under a hard hat to provide thermal protection for the head, ears, and neck region. The liner is navy blue and weighs just 0.05 pounds, making it a lightweight addition to standard personal protective equipment. It is typically installed and worn by construction workers, utility crews, and other trades operating in cold environments where supplemental head warmth is required.
This liner is suited for outdoor trade applications in cold or winter conditions. Its shoulder length offers extended coverage beyond the base of the skull, protecting the neck area during prolonged outdoor exposure. The over-brim compatibility means it is designed to fit over a standard hard hat brim rather than under it, supporting easy use with most common hard hat styles worn in construction, electrical, and industrial trades.
Designed for over-brim fitment with standard hard hats used in construction, utility, and industrial trade applications.
This liner is worn directly over the head and under a hard hat. Confirm that your hard hat accommodates an over-brim liner style before use. No tools are required for installation. Inspect the liner regularly for wear and replace if insulation or structural integrity is compromised.
