At first I was concerned that there was no string to tighten the hood. But the way it's cut, you need to put the hood up before zipping up the zipper all the way, and once it's all closed it really can't slide off. That's perfect and much more comfortable than the style that you pull tight with a string, and allows you to move your head more. I like the velcro on the back of the hood that let's you adjust its size a little.

I bought the size 4/5 for my 2 year old because another site had a good deal on it. He is 99% percentile in height, but still, he's only 2. The jacket is obviously a little big, I wanted it to last throughout next winter too, but he can already wear it. But I hope he'll get 2 or maybe even 3 rainy seasons out of it.
