This is a set of three long-sleeved undershirts for children. Blue... 130cm (Heattech, Uniqlo) Striped... 140cm (No brand) Red... 140cm (No brand) Although they are 130cm and 140cm, the sizes don't seem to differ much. All are long-sleeved, and the fabric isn't very thick. They've all been used for about two seasons, so there's a bit of wear and tear, but there don't seem to be any noticeable tears or holes. How about them for the coming cold season? ^_^
