Core warmth, unrestricted movement. The ultimate low-profile layering piece.
The Patagonia Men’s Nano Puff® Vest delivers targeted, windproof warmth right where you need it most while keeping your arms free for maximum mobility.

Filled with lightweight 60-g PrimaLoft® Gold Insulation Eco, the Nano Puff Vest delivers an outstanding warmth-to-weight ratio. Because it retains 98% of its heat-trapping power even when wet, it serves as a highly dependable layer for changeable microclimates and sudden weather shifts.
Why You’ll Love It
-
Effortless Core Layering: Engineered with a sleek, low-profile fit that slides easily over a flannel or technical fleece, and sits cleanly beneath a waterproof hardshell without bunching.
-
Micro-Packable Design: When the day warms up, the vest stuffs entirely into its own zippered internal chest pocket. The pocket features a reinforced carabiner clip-in loop so you can attach it to your commuter bag or backpacking rig.
-
Windproof Protection: A tough, 100% recycled polyester ripstop shell acts as an absolute barrier against bitter gusts, while a soft interior storm flap protects the center-front zipper from leaking cold air.
-
Sheds Light Moisture: Coated with a durable water repellent (DWR) finish made without PFAS, the fabric repels mist, morning dew, and light drizzle with ease.
-
Earth-First Craftsmanship: Built utilizing P.U.R.E.™ (Produced Using Reduced Emissions) technology to drastically lower manufacturing carbon footprints. It features 100% recycled insulation, bluesign® approved fabrics, and is sewn in a Fair Trade Certified™ factory.
