Chilly mornings in basecamp, simulclimbing by headlamp and cragging in the Creek before spring has sprung all give the Patagonia Women's Nano Puff Vest its raison detre. The latest of the Nano Puff lineage, here by demand from our customers and ambassadors alike, keeps the tradition alive with superb compressibility, featherlight weight and surprising warmth. Worn as an outer or midlayer, the vest features a premium PrimaLoft One insulation that traps heat and a 100% recycled polyester (with a Deluge DWR finish) shell that stops the wind and sheds moisture. Finer points include a drawcord hem, two zippered handwarmer pockets and an internal chest pocket (with clip-in loop) into which the vest stuffs. Recyclable through the Common Threads Recycling Program.
