About This Product

The N-Ferno 6842 Winter Hard Hat Liner has 2 layers of insulation with a polyester shell and a comfortable polyester fleece lining for exceptional warmth. This lightweight thermal liner features an extra-long neck (shoulder-length) to keep head, ears and neck covered and fits comfortably under helmets or hard hats without feeling too bulky. The PU coated 100% polyester outer shell is water-resistant and provides a durable finish that resists corrosion and abrasion. Hi-Vis lime option with reflective piping improves visibility on dark or cloudy days. 4 exterior hook and loop straps attach to the interior of a hard hat for a secure attachment and added warmth in extreme work environments. This hard hat winter liner has an elastic strip in the forehead area to keep the liner snug against the face to trap body heat in and keep cold out. Great cold weather work gear for people who spend extended periods of time in cold environments and need to wear head protection, like those in construction, freight, drilling or mining, delivery service, landscaping and warehousing. Also great for recreational use like skiing, snowboarding, sledding or other winter activities that may need a helmet.

Very nice fit right size for the hard hat
  • Verified Purchase
These are super warm and love how they also cover the neck. Thin materials also make wearing a hard hat easy.
  • Verified Purchase
This is just what I needed. It fits comfortably under my hard hat and keeps my head and ears warm. The one size fits all is very convenient. I wear it even when I'm not at work.
