The N-Ferno 6851 Fleece Winter Hard Hat Liner is designed to be worn under hard hats and safety helmets, delivering warmth in cold, demanding environments.

Made of high-quality thermal fleece, this hard hat liner features a dual-layer fleece lower section for added warmth and a single-layer on top for lightweight comfort. The full-length design provides coverage of the head, ears and neck, while still fitting comfortably under a helmet or hard hat without added bulk. Extended back coverage tucks into jackets to help seal out cold air and reduce exposure when working outdoors, while the 4-way stretch fleece allows this liner to accommodate a variety of head sizes comfortably.

Four exterior attachment points integrate with hard hat or helmet suspensions, and a hook & loop strap around the chin provides an adjustable fit that keeps the liner securely in place.

Built-in ear pockets allow for optional warming packs (sold separately) to boost warmth in extreme conditions. For increased safety in low-light environments, reflective accents help improve wearer visibility and awareness on the jobsite. This liner is machine washable for easy care and maintenance.

Ideal for those in industries that require extended periods of time in cold environments and need to wear head protection, such as construction, freight, drilling, mining, delivery service, warehousing as well as leisure activities such as skiing and snowboarding.
