Patagonia Down Sweater Vest - Men's Down Sweater Vest by Patagonia is an ultra premium alternative. Wear this and be warm. I like this for layering under a shell when I go skiing. Even better for cool nights while backpacking and chilling after dinner. Made for high altitude, low attitude. Well, I need an attitude adjustment I've been told. More than once. Either way, the Down Sweater Vest is a great piece of Patagonia. FEATURES of the Patagonia Men's Down Sweater Vest.
