The new women's Burton [ak] long baker down insulator jacket is the warmest insulator in our fleet and boasts an extra-long silhouette for additional core-hugging coverage. The secret to its popular warmth-to-weight ratio is 800-fill down, which traps a high degree of heat due to exceptional loft. Buttery soft and lightweight shell fabric sheds rain and snow, while a flattering Quilt pattern and articulated fit are a perfect look for apres style during village walks or down days around town. Lifetime Warrenty on all AK gear.
