The Patagonia men's Nano Puff jacket features PrimaLoft Gold Eco for excellent thermal efficiency. This warm insulation is also highly compressible, lightweight, water-repellent, and warm—even when wet. The lightweight shell and lining fabric is made of 100% recycled polyester and uses interlocking fibers that enhance the performance of the material's durable water-repellent (DWR) finish. Light, windproof, and warm, the Nano Puff pullover is most appreciated by the ambitious climber who wants excellent performance and a pared-down lightweight design.
