The legendary Macpac Mens Halo Down Jacket is warm, compact and a great all-rounder perfect for urban adventures, travel, hiking and camping. Filled with 600 loft Responsible Down Standard (RDS) duck down and featuring elasticated cuffs and an adjustable hem, this jacket works to keep you warm by trapping heat against your body. The lightweight nylon outer fabric (and lining) is bluesign approved and features a short-chain C6 water repellent finish to protect against moisture. A separate stuff sack is included for convenient storage when packing your bags for the next adventure. The Responsible Down Standard (RDS) is an independent, voluntary global standard in the ethical sourcing of down and feathers the RDS ensures our down comes from humanely treated ducks and geese and helps to provide traceability in our supply chain. All our down is 100% RDS certified. Similarly, bluesign certification confirms these specific fabrics have been manufactured with responsible use of resources and the lowest possible impact on people and the environment. Both the outer and lining fabrics are bluesign certified in the Halo Down Jacket.
