As you can see there are lots of high quality wool options. Merino wool, Lambswool and Shetland wool are all excellent and are actually remarkably good value considering how well high quality woolens last if taken care of properly.
My Favourite woollen is a Chevalier Orkney Sweater, which is very comfortable and very warm during those winter days
