Double Gauze Long-Sleeved Pajamas We've removed anything that might irritate the skin, such as seams under the arms and tags around the neck. The double gauze, woven softly from organic cotton, is a material with excellent breathability and moisture absorption/release properties. It's the perfect fabric for pajamas, absorbing sweat while you sleep and keeping your skin comfortable until morning. The light feel allows you to relax your body. - Size: M - Material: Organic Cotton - Color: Light Pink - Design: Collared, Chest Pocket
