Well, when you're right, you're right! The pants don't actually have belt loops. What I saw before seem to be some sort of pleat? I also grabbed a shot of the front, but there isn't much going on there.
EDIT: If the Utility Pant wasn't the base, then it was something similar. The back pockets are almost a perfect match, and the pant has the same pleat/seam over the pocket. Although, the Utility Pant has just one centered over the pocket, and the show has two on either end of each pocket.
