The Sundowner is our technical go-to for strategic warmth in cold, damp conditions. It combines water resistant 600 loft HyperDRY RDS duck down with a recycled Pertex Quantum nylon outer fabric for thermal efficiency in varied environments. As well as being 100% recycled and bluesign certified, Pertex Quantum is ultralight and soft to the touch with a DWR finish for improved moisture repellency — helping to keep the moisture on the outside and the warmth on the inside. This jacket also has a zip-off hood and everything conveniently packs into the internal pocket. Perfect for chilly weather and cold adventures. The main and inner fabrics are bluesign certified, which means they were manufactured with the responsible use of resources. The Responsible Down Standard (RDS) is an independent, voluntary global standard in the ethical sourcing of down and feathers. All Macpac down is 100% RDS certified. A technical jacket for cold, damp conditions. Made with water resistant down and ultralight Pertex nylon.
