The Patagonia Men's Better Sweater® Fleece Vest is made from 100% recycled polyester fleece, with a knitted exterior and soft fleece interior, providing warmth and comfort. Low impact dyeing reduces the use of dyes, energy and water compared to traditional methods. The full-zip design features a stand-up collar for extra protection from the cold, while offset shoulder seams keep you comfortable while wearing the pack. Zippered handwarmer pockets provide space for essentials. Abrasion-resistant micropolyester jersey trims on the armholes and hem maintain the shape of the garment. Produced in a Fair Trade™ certified factory, this vest reflects Patagonia's commitment to ethical and sustainable manufacturing practices.
