Patagonia's best-selling Nano Puff Jacket and iconic R2 fleece are combined for a hybrid that will keep you warm but not overheated during those high-output adventures.
A combination of favorites: compact weather-shedding Nano Puff insulation up top, and high-loft R2 fleece everywhere else. The PrimaLoft One synthetic insulation (60-g) with a recycled polyester shell in the upper torso and upper arms concentrates warmth in crucial areas, while the compressible and stretchy R2 fleece insulation breathes without restriction, enabling high reaches on cold-weather rock walls and unrestricted pole plants on long and frigid ski approaches. Details include two Napoleon chest pockets (harness and pack compatible), a microfleece-lined neck and chin for comfort, and a full-length, reverse-coil front zipper that's backed with a low-bulk wind flap and treated with a Deluge DWR (durable water repellent) finish.
