Powerful warmth in a light, packable layer, the Patagonia Down Sweater is the modern standard for alpine missions and extreme weather anywhere. The weather-resistant outer fabric is extremely light and has a good amount of abrasion resistance. The Traceable down is third-party certified to be non-live plucked and supplied from a facility that does not practice force feeding. Quilted construction keeps the down in place and the clean design is roomy enough for added base layers
