Built from hand-stretched mulberry silk using traditional methods, each layer is carefully stacked and stitched for consistent weight distribution and breathability. Pure natural fill that molds to your needs with no synthetics or cold spots. Use a single core for lighter coverage or layer two together for extra warmth.
