The N-Ferno 6472 Insulated Bib Overalls are designed to be worn over work pants for warmth and durability in cold environments. The 300D polyester oxford with breathable water-repellent coating protects from the elements, while the thermal insulation and quilted lining keeps workers comfortably warm. These black winter work bibs hide dirt and feature reinforced knee patches for long-lasting wear. A heavy-duty front zipper closure, comfortable elastic-stretch sides and full-length zippered pant legs make for easy on/off without removing boots. Adjustable non-slip elastic straps allow workers to get the perfect fit. For convenient storage, these work bibs have one chest pocket and two side pockets. Reflective accents keep workers safe and seen. These insulated bib overalls are ideal for those who work in cold environments where hi-vis is not required, including refrigeration, transportation, airlines or agriculture.
