I think the best base layers are made of merino wool. This material wicks away moisture if you get a little sweaty, retains insulation properties even when damp. But what to me really sets merino wool apart from synthetic materials it somehow resists odor and funk better than anything else in my experience. Also, unlike poly-based base layers, it won’t melt, which is good if you are ever warming up around a fire.
