We've eliminated the side seams for comfort and added a brushed finish for warmth. The cotton is organic. [Material] Using two-ply yarn and a brushed finish, we've created a soft and fluffy material. [Design] These long-sleeved pajamas are made from 100% cotton flannel for a soft feel. The double-sided brushing provides a smooth touch against the skin, and the absence of side seams makes it easy to turn over in bed. The collar can be worn open or buttoned up, offering a 2-way design. The contrasting piping adds a design accent.
