FIG. 5 is a top perspective view of the design illustrated in FIG. 1 with the slit in the waist area of the trousers closed and the zippered panel closed, the left side view being identical; and,

The tonal grey shaded portions on the inside of the trousers and on the side gusset of the trousers are to provide contrast only and do not indicate a color or a type of material of the claimed design.
The small evenly spaced dotted lines on the pants represent claimed stitching. The broken line at the end of the legs in FIG. 4 represent a symbolic break for the fragmentary view and forms no part of the claimed design.
