The Women's Patagonia Nano Puff Jacket is a lightweight insulated jacket for active adventures in the mountains. The horizontal brick quilting keeps the 60g PrimaLoft Gold Insulation Eco in place, which provides incredible warmth for its weight, and delivers heat even if it gets wet. This packable jacket stuffs into the internal chest pocket when not in use, while the two zippered hand pockets make it easy to stash a pair of lightweight gloves.
