The N-Ferno 6842 Winter Hard Hat Liner features two layers of insulation, with a water-resistant shell and soft polyester fleece lining for comfortable warmth. This lightweight shoulder-length thermal liner is extra long to keep head, ears and neck covered while fitting comfortably under helmets or hard hats without bulk. The PU-coated polyester shell is water-resistant with a durable finish that resists corrosion and abrasion. The 100% polyester fleece lining is incredibly soft for comfortable all-day wear. A hook and loop chin strap comfortably secures this winter liner, while four exterior hook and loop straps securely attach to hard hat suspensions for warmth on the jobsite. An elastic rim on the forehead keeps the liner snug to trap heat and keep cold out. This winter liner is ideal for those requiring head protection.Note: This is a non-returnable item.
