These overalls are designed with 200g of 3M™ Thinsulate™ insulation, a cutting-edge solution that efficiently traps heat to keep you warm even in the most extreme cold. The insulation's performance is assessed using CLO ratings, a measure of thermal resistance indicating the insulating capability. To determine temperature ratings, factors like CLO, Metabolic Equivalent of Task (MET), and task duration are considered. N-Ferno 6479 Freezer Bib Overalls have a CLO rating of 2.59 and are rated for moderate work in temperatures as frigid as -50°F // -46°C for up to 5 hours (or up to a full 8-hour workday at -45°F // -43°C).
