This is our warmest down jacket for babies. It layers easily and has an insulated hoody and soft, smocked internal elastic at the cuffs to keep out drafts. The shell fabric is NetPlus® 100% postconsumer recycled nylon ripstop made from recycled fishing nets to help reduce ocean plastic pollution. Insulated with warm, compressible 700-fill-power 100% Recycled Down (duck and goose down reclaimed from down products). GUC Slight stain on upper left side. I have not tried to get it out.
