550-fill-power duck down meets 100g of Columbia's superior synthetic insulation in a street-friendly design that also happens to be one of the warmest, softest, and lightest-weight jackets they make. The Gold 650 Turbodown Jacket's performance-enhanced down insulation delivers supreme heat retention, even when wet, and its premium ripstop shell fabric is water resistant and looks great against snowy winter backdrops on the mountain or in town.
