550-fill-power down meets 100g of our superior synthetic insulation. The result? Gold 650 Turbodown™! And the warmest, softest, and lightest-weight jacket we make. The Gold 650 Turbodown Hooded Jacket’s performance-enhanced down insulation delivers supreme heat retention, even when wet, and its premium ripstop shell fabric is both water resistant and looks great against snowy winter backdrops.
