Something you might want to try is a wild rag. It's made out of silk. Fold it in a triangle give it a couple of twirls to the size you want cross it on the back of neck tie a loose square knot in front tuck it in around your collar and you'll be surprised how much warmer you will be. You might not think that silk could keep you warm but it will. And if there is a lot of wind you can ppullit up over your face.
