The fabric of the camouflage/ice jacket bomber jacket features a heat-sensitive coating, which changes colour at low temperatures. The molecules of the micro pigments encapsulated in the external coating change the direction of light and vary in tone depending on temperature. When exposed to cold, the camouflage print will fade away and the jacket will tend to get dark grey. Due to it particularities, this fabric is very sensitive to UV rays. As a result the colour of the jacket may change over time.
