Patagonia W Nano Puff vest

• Insulation: It uses Patagonia’s Nano Puff insulation, which is made from 100% recycled polyester. This insulation is highly compressible, providing excellent warmth-to-weight ratio and retaining heat even when wet.

• Shell: The vest features a lightweight, durable, and water-resistant 100% recycled polyester shell with a DWR (durable water repellent) finish to repel light rain and wind.

• Fit: It generally has a slim, athletic fit that allows for easy layering over base layers and under jackets. The design aims to provide warmth without adding unnecessary bulk.

• Design: The vest includes a full-length front zipper, zippered handwarmer pockets, and an internal chest pocket that doubles as a stuff sack for convenient packing. Some versions may also feature a lightweight, elasticized hem to help trap warmth.

• Eco-Friendly: Patagonia emphasizes environmental responsibility, and the Nano Puff Vest is crafted from recycled materials, reflecting the company's commitment to reducing its ecological footprint.

The Nano Puff Vest is great for layering in cooler conditions or as an outer layer in milder weather, making it versatile for a range of activities and everyday wear.
