The Halo Hooded Down Vest is warm, compact and perfect for transitioning into (or out of) winter. Filled with 600 loft Responsible Down Standard (RDS) duck down and featuring an adjustable hood and hem, this jacket works to keep you warm by trapping heat against your body. To complement this, the lightweight nylon outer fabric and lining are both bluesign approved, with a short-chain C6 water repellent finish to protect against moisture. The Responsible Down Standard (RDS) is an independent, voluntary global standard in the ethical sourcing of down and feathers. All our down is RDS certified. Similarly, bluesign approval confirms these fabrics have been manufactured with the responsible use of resources.
