Trousers in Wool FlannelBusiness time. Our buttery soft, 100% wool flannel is a go to as soon as autumn leaves start to fall. It makes up beautifully in our house cut, with just enough body to drape well and keep you comfortably warm. Flannel trousers in a solid gray are the tailored equivalent of a good pair of jeans, working perfectly with your sport coats, polos, and sweaters. We really love them with a striped tee and a piece of casual outerwear. Pictured here in Navy.
