According to Wikipedia (20-Feb-2017):

The Extended Cold Weather Clothing System (ECWCS) is a protective clothing system developed in the 1980s by the United States Army Natick Soldier Research, Development and Engineering Center, Natick, Massachusetts. The first generation ECWCS consisted of parka and trousers plus 20 other individual clothing, handwear, headwear and footwear items which are used in various combinations to meet the cold weather environmental requirements of the US military (and others). The Gen III ECWCS is designed to maintain adequate environmental protection in temperatures ranging between -60 and +40 Fahrenheit (about -51 and +4 Celsius).
