Each used Patagonia® Worn Wear® style is inspected for quality, expertly cleaned and backed by our Ironclad Guarantee. The Micro Puff® Jacket combines ultralight Pertex® Quantum shell fabric with PlumaFill insulation, and the result is the best warmth-to-weight ratio of any jacket we’ve ever created and the highest compressibility of any of our synthetic jackets. It's your go-to insulation piece for mixed (and possibly miserable) cold conditions. The shell fabric is built with NetPlus® 100% postconsumer recycled nylon ripstop made from recycled fishing nets, and the insulation is 100% recycled polyester. Made in a Fair Trade Certified™ factory.
