I agree with wool, haven't tried kashmere. But the word with this is; quality. I bought myself a classic, slim, black coat made of Italian wool, and it is wonderfully warm, and at the same time probably my favourite garment, since it doesn't look "big" or thick, it is very well designed. I hope I do not sound as if I am full of myself, but I love my coat. I live in Scandinavia, and it does get cold in winters here, but I am comfortably warm in my woollen coat.
