The Diamond Stitch Down Jacket is made using Pertex Quantum, an ultra-thin nylon that is lightweight, water-repellent, and has excellent tear resistance and seam strength. The interior of the garment is then padded with goose down feather for superior warmth and comfort when you need it most. Additional details include a stand collar, elasticated cuffs and hem, and side hand pockets as well as a zip pocket at the chest. Reflector prints are implemented to enhance nighttime visibility.
