I wanted a lightweight raincoat for my five-year-old that would be enough coverage by itself, and also light enough to be worn over a sweatshirt. It's just a tiny bit thicker than what I was expecting and not really a true shell but rather a very light jacket. It runs basically true to size but is a loose fit, which I like because I feel like my daughter will (hopefully) get two seasons' use out of it. Great jacket for a great price, I am very satisfied.
