Our warmest one-piece bunting has a shell made of NetPlus® 100% postconsumer recycled nylon ripstop made from recycled fishing nets to help reduce ocean plastic pollution and is insulated with 700-fill-power 100% Recycled Down (duck and goose down reclaimed from down products). Lined with soft recycled polyester fabric, this bunting has a generous length to help keep extremities protected whether your little one is crawling, standing or sitting. Used only one season, less than a handful of times. Fit is on the bigger size.
