These are super nice jackets! I was pleasantly surprised. I ordered a 5T for my son who just turned 3 (that's the size he wears, he's big for his age) but I saw they ran a little big and I wanted him to have a little growing room too. It is just the right amount of oversized room. I think this will definitely last us until next Spring. Seems like a quality product. His favorite color is green & he's obsessed with construction vehicles, so this was perfect. Also, ordered from a 3rd party seller, "UnbeatableSale" (with hesitation- had bad experiences in past) but everything was perfect. 10 stars ✨My 3 1/2 year old doesn't ever want to take this raincoat off! I kind of wish the base color was a blue or red instead of brown, but that does not effect product quality. The inside has a light weight "fleece" which is soft, yet won't make my son overheat. Awesome raincoat!My grandson loves the rain coat.Great product.........
