Abstract
A cold protection material includes: a front side fabric constituting a front fabric of the cold proof garment or constituting a fabric disposed inside the front fabric; a back side fabric disposed on a back side of the front side fabric; two partition members forming a space between the front side fabric and the back side fabric; a filler made of down or feathers stored in the space; an air permeable member disposed to cover a vent hole provided in the front side fabric or the back side fabric; and a sealing member fixed to the air permeable member so as to prevent ventilation at least at a portion facing the vent hole in the air permeable member. The air permeable member allows ventilation at a portion other than a portion to which the sealing member is fixed.
