Rab's Cirrus Jacket is the synthetically insulated cousin to the iconic Microlight Jacket with the same great cut and quality, but with a twist. Rather than down, the Cirrus Jacket is insulated with 100% recycled PrimaLoft Silver Luxe synthetic insulation. This is loose fill, down mimicking insulation that, unlike down, retains its loft when wet - ideal for unpredictable Scottish conditions! Men's Rab Cirrus Jacket | Insulated Jackets | George Fisher UK
