This is an Edifice wool down jacket. It's packed with down filling, making it very warm! It can also be worn with a suit. The size is 44, which I think is generally equivalent to S-M. The hood is removable. Recommended for those who like SHIPS, BEAMS, United Arrows, Tomorrowland, Nano Universe, Danton, Universal Language, The North Face, Canada Goose, Moncler, Patagonia, Green Label, etc. Material (filling): Down, Feather Color: Gray
