Patagonia Nano Puff Vest - Men's | Old Growth Green

The Patagonia Nano Puff Vest is an ultralight, breathable warmth without the bulk. Whether we’re layering it under a ski shell or tossing it over a flannel for morning coffee at camp, this core insulator keeps us warm without slowing us down.

Built with a recycled ripstop shell and filled with PrimaLoft® Gold Eco, this vest offers reliable warmth—even when wet. The slim profile layers easily, and the brick quilting not only improves insulation stability but also adds a signature look. The whole piece packs into its own chest pocket, making it easy to bring along on any mission, from alpine climbs to urban commutes.
