A personal cooling apparatus (20, 40) comprises a harness (20) constructed of perforated tubing (30) to provide air circulation over the body of the wearer (22). The tubing (30) has at least one fin (58) adjacent to the perforations (60) to enhance the induction of flow of ambient air by gas escaping through the perforations (60). The tubing (30) is extruded and has a footing strip (50) formed on it to maintain it in a specific position and to permit the tubing (30) to be attached to the interior of a garment (40). The effect is to create, at each perforation (60), a small fan, and the harness (20) thereby circulates air against the skin of the wearer (22). The tubing (30) can be sewn onto the inner or outer surface of a lightweight garment (40).
