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. These black winter work bibs hide dirt and feature 1600D reinforcements to hold up through the toughest work conditions.

For convenient storage, these work bibs have 1 chest pocket and 2 side pockets. 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.

CLO RATINGS

Insulation performance is measured by CLO ratings—which is a unit of thermal resistance that indicates insulating ability. The higher the CLO value, the higher the amount of warmth a piece of clothing provides.

To determine temperature ratings, CLO factors, Metabolic Equivalent of Task (MET) and the time or duration of a task are considered. MET levels are categorized into 3 groups:

• “Low” range (0-3 MET) // forklift driver, equipment operator
• “Moderate” range (3-6 MET) // picking & packaging, delivery drivers
• “Vigorous” range (>6 MET) // concrete work, tower climber

Some warehouses and facilities are more manual in nature, leading to higher MET levels, while others rely on automation, resulting in lower MET levels. N-Ferno 6471 Insulated Bib Overalls have a CLO rating of 1.89 and are rated at a moderate work level in -15°F // -26°C temperatures for up to 5 hours.

These winter work bibs are a great choice for warmth while resisting heavy wear and tear in industries such as mining, construction and manufacturing.
