The N-Ferno 6835 Winter Hard Hat Liner with AmpliFIRE™ Heat Reflective Lining is designed to deliver advanced cold weather warmth while maintaining compatibility with hard hats and safety helmets. Its extended-length construction provides full coverage over the head, ears and neck, helping trap heat and reduce exposure to wind and cold conditions.

Built for demanding environments, the AmpliFIRE™ aluminum insulation captures, reflects and traps body heat to enhance thermal performance. A soft fleece forehead panel and angled back design help close gaps between the liner and wearer, keeping cold air out while maintaining a comfortable fit. The extended back panel tucks into jackets for additional protection during cold weather work.

Despite its thermal insulation, the low-profile design fits comfortably under head protection without unnecessary bulk. Four exterior attachment points integrate easily with hard hat and helmet suspensions, while the adjustable hook & loop chin strap helps keep the liner securely in place during extended wear.

Integrated ear pockets allow for optional warming packs (sold separately) for added warmth in extreme conditions, and reflective accents improve visibility in low-light environments. Machine washable for easy care, this liner provides durable warmth and comfort for demanding jobsites.
