Definition & Meaning of "flannels"in English

What are "flannels"?

Flannels are a type of pants made of a soft woven fabric called flannel, which is typically made from wool or cotton. These pants have a brushed surface that gives them a slightly fuzzy texture and provides extra warmth, making them perfect for cooler weather. Flannels come in a range of styles and fit, from straight-leg to slim-fit, and are often worn casually as lounge pants or pajamas. They can also be dressed up with a blazer or sweater for a more refined look.
