Sometimes shiver-proof protection comes in small packages—like Patagonia''s Nano Puff® Vest. It punches above its weight, trapping your heat with PrimaLoft® Gold insulation (60-g) wrapped in a windproof and moisture-shedding 100% recycled polyester ripstop shell with a DWR (durable water repellent) finish. The vest has a shaped fit and a soft, wicking interior storm flap and zipper garage for chin comfort. Other fine points include a drawcord hem, two zippered handwarmer pockets and an internal chest pocket (with clip-in loop) that doubles as a stuff sack.
