COMPLIANT TO ANSI/ISEA 107-2020 This reflective coat is a Type R Class 2 garment with 2” ANSI/ISEA 107-2020 compliant reflective stripes for visibility and safety in low-light conditions. 3M™ THINSULATE™ INSULATION Designed with 200g of 3M™ Thinsulate™ insulation, this jacket 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.
