Women's Nano Puff Pullover by Patagonia

The most versatile piece of insulation Patagonia makes, their new Nano Puff provides surprising warmth and terrific all-around performance in a superlight no-frills package. It's weather-resistant enough to wear as an insulated shell in a wet snowstorm, trim enough to pull on for chilly rock pitches, and warm enough for light belay parka duty on quick alpine dashes. The wind-blocking, moisture-shedding DWR (durable water repellent) finished 100% all-recycled polyester shell (1-oz 15-denier) also glides effortlessly, whether worn as a mid- or outer-layer. Low-bulk, hydrophobic, highly compressible PrimaLoft® One (60 g) traps heat with remarkable efficiency, even when wet. The Nano also packs down to practically nothing and stuffs into a single chest pocket that has a carabiner clip-in loop. Elasticized cuffs and hem seal out wind and trap warmth.
