Long-sleeved undershirt with vehicle print, black and gray striped design. - Color: Black and gray - Design: Vehicle print Thank you for viewing. I believe the fabric is similar to Heattech. There are marks on the neckline where a name tag was attached and removed with an iron. It seems Heattech-type shirts were not allowed at the nursery, so it was hardly worn. It has been stored at home, so it's for those who are not overly concerned about minor details.
