The Patagonia Nano Puff Jacket provides warmth and versatility for young adventurers who aren't easily deterred by cold. With partially recycled PrimaLoft Gold insulation, this jacket offers warm-when-wet performance and insulation that won't mat down when it gets soaked, making it perfect for long hours of snow day adventuring. We really appreciate that the DWR (Durable Water Repellent) coating ensures light snowfall and rain beads right off to keep them dry and comfortable in rough weather, while spandex binding in the sleeves and an adjustable hem block cold blasts of air.
