Patagonia Men's Nano Puff Pullover

Already a cult classic with Patagonia ambassadors and testers, the new Nano Puff Pullover for Men got top marks for versatility, 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 still see your footholds), 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 deep front zipper allows for easy ventilation. The Nano also packs down to practically nothing and stuffs into a single chest pocket that has a carabiner clip-in loop. The Men's Nano Puff Pullover is wind- and water-resistant, very warm for its weight, highly compressible and can be worn as insulation or outerwear in cold climates.
