3M™ THINSULATE™ INSULATION
Designed with 200g of 3M™ Thinsulate™ insulation, these bibs traps heat for warmth in extreme cold, ranging from -10°F to -50°F (-23°C to -46°C). The 3M™ Thinsulate™ is 30% thinner in profile compared to standard poly fill and has a higher loft design, making it condense at a much slower rate and offers more thermal retention than standard poly fill-increasing its life integrity. Minimized washing will extend the overall life of the thermal, insulated garment.
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 can be categorized as light activities (forklift driver, equipment operator), moderate activities (picking & packaging, delivery drivers) and vigorous activities (concrete work, tower climber). N-Ferno® 6477 Insulated Cooler Bib Overalls has a CLO rating of 2.59 and is rated at a moderate work level in -50°F // -46°C temperatures for up to 5 hours (rated up to a full 8-hour workday at -45°F // -43°C).
