Penalty Down Jacket Uses high-quality down with 700 fill power. Fill power is a unit that indicates the loft of down feathers. The larger the number, the more the down expands and the greater its volume. As a result, it contains a large amount of air, and due to its insulation effect, it improves lightness and heat retention. ■Color 30/Black ■Material Outer: 100% Nylon Filling: 90% Down, 10% Feather Lining: 100% Nylon
