An air-conditioning garment includes a garment main part that is worn on the upper body of a wearer, and two fans that are attached to a lower part of a back part of a garment main part, and configured to feed outside air into the inside of the garment main part. Each of the two fans includes a fan main body and a case that houses the fan main body and includes two air outlets. The two air outlets are formed so that their blowing directions are restricted to being upward or obliquely upward. The two air outlets are formed in such a manner that their blowing directions have an upwardly-opened V-shape.
