This Patagonia kids hi-loft down sweater hoody is their warmest kids coat. Super comfy and soft. Recycled nylon ripstop fabric with down insulation fill. Note to self and other parents - don’t buy a light-colored fabric! lol. As you can see in the photos, while this coat was worn by one child for 1.5 seasons, the pink nylon exterior shows staining. If you don’t care and are using this for outdoor play and activity, this coat has a lot of life left!
