I received these as gifts and only wore them once. The red one is a bit fluffy and warm inside! The light blue one is a regular long-sleeved t-shirt. The embroidery backing has been in a rough state since I received it, but my child didn't seem to itch while wearing it, so I think it's fine. It's a thin, flimsy gauze-like material. Only those who understand are welcome to purchase, thank you. m(_ _)m
