Toddling through white and drifting snow can take a while with the Patagonia Baby Down Sweater's ability to block wind and resist water lasts the journey. The ultra-lightweight 100% recycled polyester shell has a DWR (durable water repellent) finish to repel light moisture. Since Down is warmer, lighter, and more compressible for its weight than other insulating fibers, Patagonia has insulated the Baby Down Sweater with 600-fill-power Traceable Down. This baby-size down jacket has a full-length zipper with a zipper garage to protect tender chins—elastic in the back hem secures the fit to lock in warmth.
