Designed for cold storage freezer facilities with sub-zero temperatures, the N-Ferno 6476 Insulated Freezer Jacket is rated at negative 50 degrees Fahrenheit for up to 5 hours of moderate activity (CLO Value: 2.59). With 100 percent ripstop polyester and a water-resistant polyurethane coating, this cooler jacket stands up against the harshest conditions to provide warmth without restricting movement and dexterity. 200g Thinsulate insulation traps heat for warmth in extreme cold and is 30 percent thinner than poly fill. Zippered closure with snap storm flap and ribbed knit cuffs help seal out cold air. Reflective piping and high-visibility yellow material keep wearers safe and seen while on the job. Storage includes two lower exterior oversized pockets, pen/stylus holder, mic tab and two D-rings for convenient access. Machine-washable, outer-layer jacket with 28.6" long sleeves and a 33.5" long center back fits chests up to 57" in diameter and waists up to 53" in diameter.
