Abstract: A cold protection material includes an outer fabric, an inner fabric, two connecting members bonded to the outer fabric and the inner fabric so as to define a space between the outer fabric and the inner fabric, and a filler stored in the space. Each of the two connecting members has an outer surface bonded to the outer fabric and an inner surface bonded to the inner fabric, and has air permeability. Each of the two connecting members is made of a flexible material, and is configured not to be deformed so as to reduce a distance between the outer surface and the inner surface by a weight of the outer fabric or a weight of the inner fabric.
