I have been wearing LLBean crewneck sweatshirts year-'round for decades. A Double-LL polo shirt under one of these sweatshirts and a fleece over that is what I wear 90% of the time in the winter months. Pure comfort and warmth!
I washed inside out three times prior to using in order to get the pilling out of the lining material. Thanks to the lint filter on the dryer, mission accomplished.
