These long sleeve shirts are made from pure cotton and are part of our Skinkind™ range, so expect flat seams, super soft fabric and printed care instructions that do away with bothersome labels. For sizes below 8 years, the top button has an Easy Close mechanism for straight forward dressing, and our patented Expandicuff™ sleeves with cuffs that easily stretch to be slipped on and off. All of the cotton for our clothing is sustainably sourced and always will be.
