Patagonia's warmest hooded down jacket for babies, the Baby Hi-Loft Down Sweater Hoody is windproof and weather-resistant thanks to a durable 100% recycled polyester mini-ripstop shell and polyester plain-weave liner fabric, both with a DWR (durable water repellent) finish. Lofty warmth comes from 700-fill-power Recycled Down (duck and goose down reclaimed from down products).
