The Superbag comforters are constructed with 100% non-allergenic polyester insulation. The summer comforter features half ounce insulation and the winter comforter features one ounce insulation. So if you find yourself in a cold climate you don’t need to pull out any winter blankets. Simply flip your Sleep System over so the winter side is on top. The winter side of the Sleep System will be a solid color fabric that coordinates with the designer fabric on the summer side.
Made in the U.S.A.
