Not your average puffer, the Patagonia Women's Nano Puff® Hoody puts lightweight and compressible 60g PrimaLoft® Gold Insulation Eco 100% postconsumer recycled polyester to work to keep you warm and protected from wind and water. It's compressible too, with a dedicated stuff sack at the left chest pocket so you can make room for other gear in your pack. The hood isn't bulky either making it perfect for an under-the-helmet fit. Produced using reduced emissions, made from recycled polyester, and bluesign®  approved, it's hard to find a more ethically-made puffer on the market.
