YoungSoulBoys Girls Waterproof Jackets Kids Lightweight Fleece Lined Raincoat with Detachable Hood

I have a tall 5 year old who’s already nearing 120 cm height. Shall I buy 5/6 or 7/8? Don’t want it to look like a tent on him, thanks

So, how 'waterproof' are we talking? To me, "waterproof", is not really same as " can protect you in drizzle or light rain"

What size for a 4 year old? Is there a 4-5 year old size?

Is it fleece lined within the sleeves or only around back and front of the body?
