I claim the ornamental design for a sweatshirt hood, as shown and described.
FIG. 1 is a front perspective view of a sweatshirt hood;
FIG. 2 is a front view of the sweatshirt hood of FIG. 1;
FIG. 3 is a rear view of the sweatshirt hood of FIG. 1;
FIG. 4 is a top view of the sweatshirt hood of FIG. 1;
FIG. 5 is a right side view of the sweatshirt hood of FIG. 1;
FIG. 6 is a left side view of the sweatshirt hood of FIG. 1;
FIG. 7 is a front view of the sweatshirt hood of FIG. 1 in a laid-flat position with the zipper in an open position; and,
FIG. 8 is a front view of the sweatshirt hood of FIG. 1 with the zipper in an open position.
The zipper follows the curvature of the sweatshirt hood.
The dash-dot-dash broken line defines the bounds of the claim and forms no part of the claimed design. The even-length broken lines depict portions of the sweatshirt hood that form no part of the claimed design.
