The Women's Patagonia Nano Puff Vest is lightweight recycled polyester ripstop shell and has a durable water repellent (DWR) finish made without intentionally added PFAS to shed light moisture. It has 60-g PrimaLoft Gold Insulation Eco postconsumer recycled polyester with P.U.R.E. (Produced Using Reduced Emissions) technology that provides excellent warmth for the weight, stays warm when wet, and reduces carbon emissions as compared to conventional production methods. The brick quilting pattern with narrow horizontal quilt lines on side panels stabilizes insulation and uses durable thread for abrasion resistance. This center-front zipper has a wicking interior storm flap and a zipper garage at the chin for next-to-skin comfort, or two zippered handwarmer pockets have cleanly finished zipper garages; an internal zippered chest pocket doubles as a stuffsack with a reinforced carabiner clip-in loop with a drawcord-adjustable drop-tail hem that seals in warmth. Made in a Fair Trade Certified factory, which means the people who made this product earned a premium for labor.
