Picked this up for my 1-year-old daughter - it's working great so far. It's very warm yet still is OK for a car seat since it's not too puffy. The fit is roomy but that way she won't outgrow it too fast. The hood has a nice fit - it actually stays put on her head even when she's squirmy.
Works great as a go-to jacket for our daughter. Packs down small enough to fit in our diaper bag when we're on the go, but it's thick enough to keep her nice and toasty. It's a great insulator layer under her heavier winter parka and the hood is a nice addition when she doesn't want to wear a knit hat.Jacket is cut a bit larger than expected (sleeves longer and waist is wider), which isn't a bad thing since our daughter loves it so much.
