During World War II, the C-2 was an inner-wearing sweater for the mid-temperature zone or the cold zone. It can be worn inside aeronautical flight jackets such as A-2, B-3, B-6, as well as wool shirts. Since there are other clothes such as wool shirts, the C-2 is not used in large quantities. The texture is not too thick, and the wear and tear are very high. The collections that can be preserved so far are rare and of high value.
