Soft, cushy knit. It's a nice midweight sweater, not too bulky, so you don't feel chunky in it. I love the color; it's a deep, dark gray that looks so rich. Button placement is SO well done; they didn't try to chintz out with less buttons, so no gapping when you put your shoulders back. I haven't laundered it yet, but I see they say hand wash. I don't hand wash anything, so it will be put in a mesh bag, and machine washed on gentle cycle, cool water, in my agitator-less washing machine. I'm going to see what other colors they have...
