The Patagonia Nano Puff Jacket is a lightweight, high-performance insulated jacket engineered for versatility in cool to cold conditions. Featuring 60g of PrimaLoft® Gold insulation—synthetic, water-resistant, and highly compressible—it delivers exceptional warmth-to-weight ratio even when damp. The shell is made from 100% recycled polyester with a DWR (durable water repellent) finish, offering wind resistance and light moisture protection. Its signature quilted box baffling ensures even loft distribution and minimal cold spots, while the full-length YKK zipper with storm flap, stand-up collar, and two zippered hand pockets enhance functionality and comfort. The jacket includes an internal zippered chest pocket and elasticized cuffs and hem for a secure fit. Lightweight (approx. 340g for men’s M) and packable into its own pocket, it’s ideal for layering under shells or wearing solo during urban commutes, hiking, or travel. The sage green color offers subtle, earthy sophistication, aligning with Patagonia’s outdoor heritage and sustainability ethos. Designed for unisex wear with a relaxed yet tailored silhouette, it suits daily wear, casual outings, and light outdoor adventures across fall and winter seasons.
