N-Ferno 6471 Insulated Bib Overalls - Heavy-Duty 500D Nylon Shell
The N-Ferno 6471 Heavy-Duty Insulated Bib Overalls are designed to be worn over work pants for warmth and durability in extremely cold environments. The 500D polyester oxford with breathable water-repellent coating protects from the elements, while 3M Thinsulate insulation traps heat for enhanced warmth.

Zippers on each leg make it easy to pull on and take off the insulated bib overalls without removing work boots. 4-way stretch sides enhance comfort where you need it, and adjustable elastic straps make for a custom fit. 3M reflective accents keep wearers safe and seen.
