I claim the ornamental design for an underwear with pocket, as shown and described.
FIG. 1 is a front perspective view of an underwear with pocket showing the new design.
FIG. 2 is a front view thereof.
FIG. 3 is a rear view thereof.
FIG. 4 is a right side elevation view thereof.
FIG. 5 is a left side elevation view thereof.
FIG. 6 is a top plan view thereof.
FIG. 7 is a bottom plan view thereof; and,

The broken lines shown depict portions of the underwear with pocket that form no part of the claimed design. The jagged broken line shown in FIG. 8 depicts a cut line for the enlarged view that forms no part of the claimed design.
