Combining 850 fill down and a GORE(R) WINDSTOPPER(R) outer shell, the Ceres SV is built for severe cold. The goose down insulation is warm, light and efficient, and box wall construction eliminates cold spots and helps maintain maximum loft. To assure thermal performance, Coreloft(TM) synthetic insulation is utilized in areas prone to moisture, and the breathable GORE(R) WINDSTOPPER(R) shell blocks the wind and sheds light rain and snow. An insulated StormHood(TM) provides full coverage warmth and protection.
