The Patagonia Nano Puff is a lightweight, highly compressible insulated jacket engineered for versatile cold-weather performance. Featuring 60g of 100% recycled polyester insulation (PrimaLoft® Gold Eco), it delivers exceptional warmth-to-weight ratio while remaining breathable and packable—fits into its own pocket for travel. The shell is made from 100% recycled polyester with a DWR (durable water repellent) finish for light moisture resistance. Design includes a full-length YKK two-way zipper, zippered handwarmer pockets, an internal chest pocket, and a stand-up collar for added neck protection. The iconic Patagonia P-6 logo patch appears on the left chest, and the interior tag confirms authenticity. Its box-quilted construction ensures even heat distribution and minimal cold spots. Ideal for layering under shells or wearing solo in cool to cold conditions (20–40°F / -7–4°C). Perfect for hiking, urban commuting, travel, and everyday casual wear—blending technical functionality with minimalist streetwear aesthetics. The sleek black color offers timeless versatility, while the durable fabric resists abrasion and pilling. Ethically produced with Fair Trade Certified™ sewing and commitment to environmental responsibility.
