The Patagonia Nano Puff Pullover is a phenomenal cold weather top with an outstanding warmth-to-weight ratio. Although lightweight—tipping the scale at just over 8.5 ounces—it’s quite warm, making it the perfect layer to throw on when you take a ski break or during activity in colder temps. The synthetic insulation stays warm even if it gets wet (which is unlikely with its durable water repellent coating), and it’s great at cutting the wind.
The Nano Puff is also light on features, which keeps it featherweight in your pack. Its minimalist silhouette includes elastic at the cuffs and waist, a tall stand-up collar, and a deep front zip (perfect for venting when you heat up). The pullover has a roomy cut to fit easily over layers, and its single pocket, a chest pocket, doubles as a mini stuff sack. When you need to pack it up, it makes a compact little package with a carabiner loop.MSRP $149 The Nano Puff is also available in full-zip and hooded styles.
