The Patagonia Nano Puff Jacket is a lightweight insulated layer designed to deliver reliable warmth without bulk. Originally created for climbers who needed a packable, weather-resistant synthetic jacket, it has evolved into a go-to midlayer for nearly any outdoor pursuit.

Engineered with 60-g PrimaLoft® Gold Insulation Eco, it provides exceptional warmth for its weight and continues to insulate even when wet. The 100% recycled polyester shell and lining feature a durable water repellent (DWR) finish made without intentionally added PFAS, helping shed light moisture in unpredictable conditions. With improved mobility through refined shoulder shaping and elbow articulation, this updated version is built for active movement in the mountains or the city. Compact, durable, and highly versatile, it’s the jacket many refer to as the “magic jacket” for good reason.
