The men's Down Sweater from Patagonia is the perfect balance of warmth for just about any outdoor activity. Patagonia created a classic, newly redesigned Down Sweater that is lightweight and windproof. Patagonia understands that where you source your materials is important. That is why the shell is made from 100% postconsumer recycled nylon ripstop made from recycled fishing nets to help reduce ocean plastic pollution. As far as the insulation goes, it is made from 800-fill-power 100% Responsible Down Standard down certified by Control Union. The purchase of Responsible Down Standard certified products demonstrates demand for better animal welfare practices in the down and feather supply chain.
