We are always told to never use flannel for the bag, only for a removable cover. Flannel should never be microwaved, it has a lower flash point than cotton I think, and is more likely to burn.
Yes, the flannel cover is removable. That way it keeps the inside bag clean and the flannel can be washed.
Thanks for the heads up on the burn danger, though!
