Micro flannel® fabric sheet sets are an innovation that combines the soft and luxurious feeling of high quality European cotton flannel with the easy care benefits of polyester fleece. Micro flannel® is so soft and luxurious and it provides warmth without weight or bulk. It is anti-pill, doesn’t shrink like cotton flannel, resists wrinkling, and breathes so you are so comfortable on all those chilly nights. Micro flannel® is color fast. It is also energy saving because it is fast wash and quick dry.
