Impossible to answer, being comfortable temperature wise is completely dependent on the individual. Most people would freeze to death dressing like I do. I went two seasons out here in CO wearing nothing but softshells with at most a light base layer and light fleece long sleeve shirt underneath. Subzero temps, whatever. I've just always been naturally hot natured.
