A climate-controlled hand grip assembly that uses one or more air jets or air channels directed at a tangent to an outer surface of the hand grip assembly. The outer surface may be curved and the air flow path may bend with the curve to provide a film of conditioned air along the outer surface that spreads beyond the point of origin of the air flow path. An exemplary embodiment of a steering wheel device with a rim and spokes is disclosed wherein the outer surface of the rim, spokes or both can be enveloped with conditioned air using a Coanda Effect.
