I just got an Amphipod Xinglet for running in the pre-dawn hours. The images I have seen of the product appear to imply that the waist strap would actually fit somewhere around the waist. However, even with the height belt loosened entirely, the waist strap is above my belly button at rest and rides up another inch or so when I'm running, to just below my rib cage. Is this how it fits other runners, or do I just have a freakishly long torso?
