The fabric features a soft feel with no side seams for comfort. The cotton is organic. The softly woven double gauze cotton is highly breathable. It absorbs sweat while you sleep and keeps you comfortable until morning, making it the perfect material for pajamas. The gauze is gentle on the skin, and the loose weave makes it light and soft, and the double layer also creates an air layer inside. This material can be worn all year round, regardless of the season.
