It consists of a striped top with a contrasting collar and front snap buttons; and plain shorts, with a soft and flexible waistband. Printed inner labels to avoid irritating the skin. 2-in-1 pyjama, with appliqué at the base of the top and on the side of the shorts, to ensure the pieces stay together all night and thus guarantee greater thermal comfort.
