Anyone know what is considered a heavyweight fleece or terry? I have been searching for some time and heavyweight seems to be the most vague. Is there another factor besides fabric weight that can translate to warmth? I found many heavier materials being used but I really can't pin down what will be the warmest for a northeastern US sub zero winter. I will just have to go with the heaviest since it means higher density, more air being trapped, and therefore the warmest.
