Stone Island David TC Jacket in Off White. A direct result of their extensive research and development into fabrics and dyeing techniques, the David TC material is a polyester and polyamide blend sourced in Japan. The garment is initially sewn together and then simultaneously dyed under pressure at 130 degrees celcius and given an anti-drop treatment. The material is then given a heat-induced pressure treatment which transforms the way it feels, resulting in a good looking and wearable garment that is industrial and luxurious. This hooded parka jacket comes with an inner removable down filled gilet.
