My son is 12 years old (size 10/12 is usually small and 14/16 is usually large) and has one athletic, thin side. XLarge fitted him perfectly in a form-fitting hoodie. It will probably only last until March/April, which suits us. He really likes that it's not chubby and that it fits in a pocket and he can put it in his locker. I like the closed zip that doesn't scratch his neck and that the collar is slightly snug to keep cold air out. I bought 4 jackets and returned them before finding this one and I am very happy with the purchase and so is my son.
