Smart sweatshirt that is based on three layers:
The first layer which is closest to the skin is a silver reflective coating, allowing for great thermal conservation.
The middle layer is the most sophisticated. It contains red, green and blue lights controlled by open source Arduino chips.
The visible outer layer is waterproof, made of thin translucent fabric.
In addition, each sleeve includes a color sensor, so that the color of the jacket gets to adapt the color of the touched object.
