  • air exit portions are to be provided by a collar portion, sleeves, and hemline of the T-shirt.
  • the guide sheet (garment) may have a certain air permeability depending on a purpose, insofar as sufficient parallel airstreams can be flowed by a fan(s) providing a larger air blowing amount.
  • a fan(s) providing a larger air blowing amount.
  • the effect thereof is improved by providing a guide sheet (garment) having a smaller air permeability in such an area only.
  • a cloth having a due air permeability since airstreams will then impinge on arms when the arms are moved.
  • the electric-power source means is not limited to a battery, and may be a commercial-power supply.
  • the present invention as described above, it becomes possible to cause a large amount of air to flow parallelly to a wearer's body so as to largely extend an effective area under the influence of a physiological cooling ability of the wearer to thereby assuredly cool the wearer's body even in a situation where a large amount of perspiration is exuded. It is thus possible to apply the present invention to a cooling suit to be used for cooling a wearer's body in a situation where a large amount of perspiration is exuded.
