UPDATE 12/4: Some small holes and loose threads, as well as some piling around the sleeve. (See photos at the end.) The jacket is still functional. Size M Patagonia Nano Puff Insulated Jacket. Warm, windproof, water-resistant—the Nano Puff® Jacket uses incredibly lightweight and highly compressible 60-g PrimaLoft® Gold Insulation Eco 100% postconsumer recycled polyester with P.U.R.E.™ (Produced Using Reduced Emissions) technology, wrapped in a 100% recycled polyester shell and lining. Made in a Fair Trade Certified™ factory. Used, good condition. Selling because it's too small for me now!
