Thanks for getting in touch. The Sea to Summit Ember Quilt, with its 850-fill down, offers great insulation and warmth, making it suitable for cooler conditions. However, whether it works for winter depends on the specific temperatures you'll be facing and your personal comfort level. For milder winter conditions or if you layer it with other gear, it could work well. But for very cold or extreme winter temperatures, you might want to consider something specifically designed for those conditions.
