The Patagonia Women's Nano Puff Vest blocks wind, insulates warmth and sheds moisture for your core while leaving your arms unencumbered and mobile. 100% recycled polyester shell surrounds PrimaLoft One insulation, and both materials are treated with Patagonia's Durable Water Repellent (DWR) Finish. This lightweight, highly compressible vest can stuff into an external zip pocket that has a carabiner clip in loop, making it great to bring along for climbing, hiking and canyoneering as a "just in case" layer when conditions may vary, in other words: always. The low-bulk Patagonia Women's Nano Puff Vest can function as a smooth, insulating mid layer and can also be worn as outerwear.

• Deluge DWR Finish - Patagonia's proprietary durable water repellant finish functions like new even after years of extensive use
• PrimaLoft One - lightweight 60 g polyester insulation retains body warmth and is impressively compressible
