Worn as an outer or midlayer, the Patagonia Women's Nano Puff® Vest uses PrimaLoft® ONE (60-g) insulation for superb compressibility, featherlight weight and surprising warmth.
All of this is wrapped in a windproof and moisture-shedding 100% recycled polyester ripstop shell with a Deluge® DWR (durable water repellent) finish. The fit has been improved with better shaping through the torso and waist, and a soft, wicking interior storm flap and zipper garage has been added for chin comfort. The classic Nano Puff "brick" quilt pattern has been redesigned adding narrow horizontal quilt lines on the side panels, and using a burly thread for enhanced durability.
Other features include a drawcord hem, two zippered handwarmer pockets and an internal chest pocket (with clip-in loop) which doubles as a stuffsack.
