The Men's Patagonia Down Sweater Lightweight Pullover is an insulation piece for everyday wear. Built like a technical piece but ready for travel, the recycled nylon ripstop fabric and 800 fill power down make it easy to pack into carry-ons or messenger bags. It brings heat to any cold day, without the weight. The half-front snap placket makes it easy to adjust temperature on the fly, plus a hood for head warmth. Warm your hands in the front pockets, and the zippered interior chest pocket converts into a stuff sack.
