The Patagonia Nano Puff® Vest delivers lightweight warmth without bulk, making it an essential layering piece for cold-weather activities. Using 60-g PrimaLoft® Gold insulation, this vest traps heat efficiently while remaining highly compressible. Its 100% recycled polyester ripstop shell with a DWR (durable water repellent) finish blocks wind and sheds moisture, keeping you dry and warm in variable conditions.

Designed for comfort and functionality, the vest features a shaped fit, soft interior storm flap, and zipper garage to protect the chin. Additional details include a drawcord-adjustable hem, two zippered handwarmer pockets, and an internal chest pocket that doubles as a stuff sack with a reinforced clip-in loop. Its brick quilting pattern stabilizes insulation for consistent warmth.
