It wasn’t very thick but wasn’t too thin neither. It didn’t run small so I would size up atleast 1 to 2 sizes. My son loves it, but since it ran small he’s going to outgrow it a lot quicker than his other 10/12 clothes. It fit more like an 8. But I do know not every brands sizing fits the same. So it’s more fitted too him than his usual hoodies. He usually likes them a bit looser and baggy so not only does he have growing room, but he can wear t shirts under them. This one he can’t do that. But other than the sizing issue, I’d say this is a win since he’s happy and love SpongeBob!

Can’t wait to give to my son for Christmas but it looks great!
