Each used Patagonia® Worn Wear® style is inspected for quality, expertly cleaned and backed by our Ironclad Guarantee. We built the Nano Puff® Vest for climbers who needed a weather-resistant, lightweight and packable synthetic insulation layer that could stay warm even when wet and withstand seasons of use. Ever since, those same features have made it the uncontested favorite midlayer for just about any outdoor pursuit. With fit refinements for improved mobility, insulated with 60-g PrimaLoft® Gold 100% postconsumer recycled polyester with P.U.R.E.® (Produced Using Reduced Emissions) technology, and a 100% recycled polyester shell and lining. Made in a Fair Trade Certified™ factory.
