Great design but needs some insulation for core
The baby really likes the arms up option and now with rolling we have removed the covers to allow arms free. The only suggestion for improvement is to add insulation to either the back or chest. The thin stretchy material has no heat retention and since core temp is about the chest it would help keep the baby warm more evenly. The lose arms openings also are a spot for heat loss. But overall recommend these for babies that like sleeping arms up swaddled and for the transition to arms free.
