Patagonia Retro Pile Vest The Patagonia Retro Pile Vest is a mid-layer or outerwear piece that offers exceptional warmth and versatility. Made from plush 100% recycled polyester double-sided shearling fleece, it provides incredible comfort and easy-wearing insulation. Its full-zip design with a zip-through stand-up collar allows for precise temperature regulation. At the same time, offset shoulder seams ensure optimal comfort for pack-wearers and enhance long-term durability. Thoughtfully designed with mesh-lined zippered pockets - including one chest pocket and two handwarmer pockets - the vest combines practical storage with sleek functionality. Finished with elastic binding on the collar, armholes, and hem, and featuring flat-seam construction to reduce bulk and minimize chafing, this Fair Trade Certified™ vest represents Patagonia's commitment to both performance and ethical manufacturing. It provides you with a versatile layering piece that doesn't compromise on comfort or sustainability.
