Love these jackets. I found the first one at goodwill and both my kids wore it for over 3 years until they outgrew it and I saved it for my 3rd boy. I found this same one online and bought it. Fits perfect on my 4 year old who is a little big and tall for his age. He is about 55lbs now. It should fit him for another year. Carters tends to run right and small on my kids generally, but I think these jackets fit true to size. Super cute, super durable, super comfortable for playground and outings because it’s thin, but warmer than a sweatshirt for windy and chilly days. Buy it!
