N-Ferno 6472 Insulated Bib Overalls are designed to wear over work pants for warmth and durability in cold environments. 300D polyester oxford with breathable, water-repellant coating protects against the elements. Thermal insulation and quilted lining keep workers comfortably warm. Black winter work bib hides dirt and features reinforced knee patches for long-lasting wear. Heavy-duty zipper closure, comfortable elastic-stretch sides and full-length zippered pant legs allow easy on/off without removing boots. Adjustable, nonslip elastic straps provide the perfect fit. One chest pocket and two side pockets provide convenient storage. Reflective accents keep workers safe and seen. Machine-washable overalls are ideal for those working in cold environments where high visibility is not required, including refrigeration, transportation, airlines and agriculture. They are also great for outdoor recreational activities such as snowmobiling or hiking.
