Sometimes shiver-proof protection comes in small packages, like our Nano Puff Vest. It traps your heat with 60-g PrimaLoft Gold Insulation Eco, now with 100% postconsumer recycled content, 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, a pair of zippered handwarmer pockets and an internal chest pocket (with clip-in loop) that doubles as a stuff sack. Fair Trade Certified sewn.
