There is a rule in winter camping. Cotton is rotten.
Cotton absorbs and holds moisture.
Synthetic and silk let moisture pass through in to the next layer.
If you wear a synthetic on the skin then cotton over it the cotton will take the sweet off the synthetic. Cotton can be bleached (white) which will reduce the smell.
