Heat Reactive Jacket by Stone Island

Experts in fabric development, Italian outdoor wear label Stone Island has come up with a new heat reactive jacket that fuses fashion fun with scientific experimentation.
At 27 degrees celsius, the liquid crystal molecules used in the jacket fabric start to rotate, changing the path of light reflected onto them and turning the jacket from black to green. When the fabric returns to room temperature, the colour returns to normal.
Designer Carlo Rivetti says: "The point we started from is active camouflage – a garment that changes according to its environment. The culture of research and experimentation, together with function and use, are the matrixes that have always defined Stone Island. Fashion is not really relevant for me; my priority has always been to create great product.” The jacket retails at around £500.
