Thank you for looking. All sizes are 150. I am listing them because my child did not like the stripes. All are long-sleeved and made of thick, sturdy fabric, so I think they are perfect for the coming cold season. Although they are an unknown brand, I liked that they were 100% cotton and not thin, so I bought three new ones at the same time. You can tell by the feel that these long-sleeved shirts are 100% cotton and will be comfortable to wear. If you have any other questions or would like to see more photos, please feel free to ask in the comments. I will fold them compactly and compress them for shipping, so there is a possibility of wrinkles. Please understand that these are inspected by an amateur and are used items. I ask for your understanding in the unlikely event of any issues.
