Abstract: A carrier device for umbrellas has a shoulder engaging hook and stabilizer affixed in spaced relation on the lower end of the umbrella shaft. The shoulder hook is concave to conform to the shoulder of the wearer and its free end is angled toward the middle of the back for more secure gripping. The stabilizer is disposed below the shoulder hook and is vertically curved to conform to the upper torso of the wearer and has a concavely curved upper edge to accommodate the arm of the user for stabilizing the umbrella. In addition, the stabilizer includes an opening to provide a handle portion whereby the umbrella may be hand held when not fitted onto the torso.
