Modern Moments by Gerber Toddler Boy Workwear Shirt, Sizes 12M-5T

This is such an adorable little “jacket”. It isn't lined since it's a work shirt, but it is a thick material kind of like a softer Carhartt. It's great for layering on cold days. I couldn't see this being comfortable worn on its own due to how thick it is so I use it as a jacket over my son's flannel or a long sleeve shirt for that extra layer of warmth. Pretty true to size, a tad larger, but I prefer it that way. Definitely suggest getting it if you're on the fence!
