The Patagonia Nano Puff is a down jacket classic by this point, and here’s why it needs to be a staple in your outdoor adventure and travel wardrobe:

Available as a jacket, hoody, or vest, the newest version of Patagonia’s tried-and-true down coat is made of 100 percent post-consumer recycled polyester. It utilizes P.U.R.E.™ (Produced Using Reduced Emissions) technology and is Fair Trade sewn.

And that’s just the stuff you can’t see or feel. Wearing the Nano Puff, you immediately understand how lightweight, breathable, and flexible this fabric is. I can hike in it, ski in it, snowshoe in it, or just wear it around town as a mid-layer or outer layer. It’s windproof and water-resistant, and when I need full waterproofing, I can pair it with a shell and not feel like a marshmallow.

The Nano Puff packs down incredibly small into its own pocket, making it easy to stash in a backpack or carry-on. It goes with me on the (few) plane rides I currently take, on every road trip as a layering piece, and on fall hiking and camping adventures. It will become my mid-layer as autumn shifts into winter.

I like the jacket (without hood) because it works better for me as a mid-layer option, but the hooded option is available, as is a vest if you just need to keep your core warm while working out. You get adjustable drop tail hems to keep out the cold, wind, or snow, and two zippered handwarmer pockets which feature cleanly finished zipper garages. There’s also one zippered internal chest pocket (this is the one that doubles as a stuffsack with a reinforced carabiner clip-in loop).

Pick up the Nano Puff jacket for $199 in a variety of colors. There’s a men’s line as well, of course!
