These pajamas are made of high-end Irish linen and hardman's. The black fabric, thick ivory piping and chest pocket embroidery of the same color create a French chic and mature look. All stitches are folded together, so there is no snagging and there is no need to worry about fraying. The solid fabric of the 40th count can be worn all year round. All pajamas come with a bag made of the same material.
