My husband is pretty obsessed when it comes to outwear for the kids. He is a big fan of layers.
He ALWAYS puts a fleece cardigan on them underneath their bigger coats. The kids had outgrown theirs from last year so we went with didriksons from little footprint.
We are very happy with them and they will be great on their own when Spring is here!
