Premium ultrasoft cotton flannel sleep pants, in just the right weight to stay warm and cozy without overheating. Classic Fit: Sits at the natural waist and trim, with a traditional straight leg. Inseams: Short 30", Regular 32", Tall 34". An L.L.Bean exclusive, the plush flannel fabric is meticulously woven with longer-staple cotton, which means the individual cotton fibers are about one-quarter inch longer than short-staple fibers, making a huge difference in fabric strength and quality. Then, it's meticulously brushed eight times on each side and given a "touch test" by a master weaver to declare it soft enough.
