I claim the ornamental design for a mask attached to a hood, as shown and described.
FIG. 1 is a front elevation view of a mask attached to a hood in a position of use as inset from the rim of the hood and covering a portion of the user's face.
FIG. 2 is a right-side elevation view thereof.
FIG. 3 is a left-side elevation view thereof.
FIG. 4 is a top plan view thereof.
FIG. 5 is a bottom plan view thereof.
FIG. 6 is a rear elevation view thereof.
FIG. 7 is a front elevation view of the mask shown in FIG. 1 stowed within the hood.
FIG. 8 is a perspective view of the mask shown in FIG. 1 covering a portion of the user's face and with the hood pulled back.
FIG. 9 is a perspective view of the mask shown in FIG. 1 with the mask stowed within the hood.
FIG. 10 is a front elevation view of the mask component of the mask attached to a hood shown separately.
FIG. 11 is a right-side elevation view thereof; and,
FIG. 12 is a left-side elevation view thereof.
The broken line outline of the hood depicts portions of the article that form no part of the claimed design. The partial human figure outlined by broken lines assists to illustrate the claimed design in a position of use and forms no part of the claimed design.
