Patagonia Men's Nano Puff Vest is a lightweight, warm and compact insulated vest designed for activities where freedom of movement and reliable warmth are essential. The vest retains heat even when damp, making it a dependable choice in changeable weather conditions. It works equally well as a warm mid-layer beneath a shell jacket or worn alone on quieter days outside.

The vest is filled with 60 g PrimaLoft® Gold Insulation Eco, a lightweight and efficient synthetic insulation made from 100% recycled polyester. The P.U.R.E.™ manufacturing process contributes to a reduced climate impact compared with conventional methods. Both the outer fabric and lining are made from 100% recycled polyester, resulting in a durable, windproof and water-repellent construction without compromising on weight or packability.

With an improved fit that allows greater freedom of movement, the Nano Puff Vest is a versatile garment for hiking, climbing and everyday use. The vest is produced in a Fair Trade Certified™ factory, ensuring better working conditions for those who make it.
