Features Fabric 12" high 16" wide Our new and improved Big Agnes System bags provide a unique draping effect that feels more like the comforter on your own bed. Rest assured, our new design, coupled with the highest quality insulation materials, delivers plenty of warmth on cold nights and room for active sleepers. When insulation material is compressed under your body, it loses most of its ability to insulate. We eliminate the unnecessary bottom insulation and replace it with one of two pad sleeve designs to accommodate the pad which provides the insulation. This design provides a secure foundation and keeps you on the pad all night.
