More important than the belt's ability to keep the loincloth and leggings in place was the ability to keep itself in place. The survivalist's adage "everything you carry should have more than one use" is not a recent realization. The belt held another surprise when examined closely. An 8" long, 2" high strip of hide was stitched onto the front of the belt in almost the exact center. The stitching was accomplished using a hide lacing that varied in width from .19" to .25" wide that went completely around the hide strip with the exception of a 3.25" opening left in the center at the top edge. It was a pouch! It even had a 6" long lace attached to one side to tie it closed.
This simple leather belt would stay with him under all but the most extreme conditions. He could lose his bow and quiver, his axe, even his outer clothes and shoes, but his belt would remain. The pouch, protected by the outer flap of his loincloth, held 5 items: his survival kit. To untrained eyes, they were worthless fragments of stone, bone and fungus but in the hands of an expert woodsman, it would give him a chance at surviving even with everything else lost.
