fleece

FLEES /fliːs/
nounadjectiveB1
neutral

A soft, warm, synthetic insulating fabric made of polyester, designed to mimic the texture and warmth of sheep's wool.

Can refer historically to the natural woolly coat of a sheep, but in modern activewear, it almost exclusively refers to lightweight, synthetic polyester insulation.

The story behind the word. Originally, 'fleece' referred strictly to the natural woolly coat of a sheep. In 1979, Malden Mills (now Polartec) revolutionized the outdoor apparel industry by inventing a lightweight, synthetic polyester fabric that mimicked the warmth of wool without its heavy weight or water retention, forever changing cold-weather sports.
