What Is Flannel, and Why Is It So Cozy?

Flannel is made of cotton or synthetic fibers that are woven and brushed to create a soft, fuzzy finish. The raised fibers—or nap—trap warm air, creating a naturally insulating effect so you stay cozy on cold nights. Flannel bedding offers many benefits. Here’s why people love it: 

  • It’s soft, breathable, and warm. 
  • It offers natural insulation on cold nights. 
  • It’s durable and long-lasting.
