Polar fleece is a plush, spongy, totally artificial material that weighs nothing and conveys no quality of warmth or coolness; in fact, you can wear it in the most bitter weather or in the hottest heat. Polar fleece looks neither flimsy and light nor hearty and warm. It has no historical, cultural, or physical association with a place, a season, a society, or any living thing. It is the first existential fabric - eminentaly useful, meaningless, dissociated and weird.
