The Patagonia Men's Nano Puff® Vest punches above its weight, trapping your heat and keeping you dry all winter long. Thanks to the 60-g PrimaLoft® Gold Insulation Eco that is now made with 100% post-consumer recycled content, makes this vest the most thermally efficient synthetic insulation available. The windproof and moisture-shedding 100% recycled polyester ripstop shell with a durable water repellent finish add extra protection ensuring you stay dry and warm. 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 a clip-in loop that doubles as a stuffsack. The Patagonia Men's Nano Puff® Vest pairs nicely with your favorite flannel and is ready to take on everyday adventures.
