How do I adjust the sternum strap on the Water Tower packs?
The sternum strap is kept in place by a white Delrin wand inside a Hypalon rubber sleeve with slots cut out for various height positions of the sternum strap. The upper right-hand corner of the Hypalon rubber has a small cutout that allows you to push the Delrin wand out, remove the wand to reposition or remove the sternum, then rethread the wand through the rubber and the webbing of the sternum strap. The advantage of this system is that there is no webbing underneath the shoulder strap to rub on your body, and the sternum can be completely removed if required.
