The N-Ferno 6853 Thermal Trapper Hard Hat Liner is designed to provide maximum warmth and thermal protection while fitting comfortably under hard hats and safety helmets. This trapper-style liner combines a durable, windproof and water-resistant polyester shell with 60 grams of 3M Thinsulate insulation and a full fleece interior to deliver exceptional warmth in cold, demanding environments.

The liner features a forehead panel that helps seal in heat while providing a soft, comfortable fit. The trapper style design with side flaps provides additional warmth and comfort around the ears and sides of the face.

Four exterior attachment points integrate seamlessly with hard hat or helmet suspensions. A chin strap with YKK adjustable buckle provides a secure, personalized fit, while a reflective accent improves wearer visibility in low-light environments. Available in three sizes. Machine washable for easy care and maintenance.

Ideal for industries requiring extended periods of time in cold environments with head protection, such as construction, freight, drilling, mining, delivery service, warehousing as well as leisure activities such as skiing and snowboarding.
