This light and warm sleeper is made of fluffy, cozy flannel material. The inside is gauze, which absorbs sweat effectively. The outside uses high-quality flannel fabric, a type of blanket material, so it feels smooth and fluffy against the skin. It's so comfortable you'll want to touch it all the time. It can be completely separated, making it easy to dry when washing. My daughter wore it for one season. There are no noticeable stains or fabric damage, and it's in overall good condition. I'm also selling a different pattern. Please take a look if you're interested.
