Chill-Its® Warming Packs
N-Ferno winter liners are designed to keep the user's body temperature within a safe range and come in a variety of styles to keep workers comfortable, even in extreme working environments. Constructed of durable fabric that offers warmth and facial protection. Economy liners are water repellent with an elastic gap control at the forehead to keep warmth in and cold out. Non-economy winter liners feature a potentially lifesaving reflective safety strip that is visible at night and designed with a spot next to the ears to hold warming packs, sold separately. To activate, simply open the wrapper and expose the warming pack to the air, providing comfortable heat lasting up to 8 hours. The easy to dispose packs contain no toxic materials and are sold 40 pairs per case.
