I'm looking at the HPG Umlindi daypack:

There is an option of adding on a Prairie Belt, if I'm inclined to load it up with something heavy.

Here's my question: Can anyone tell me if a Prairie Belt and the Umlindi's shoulder harness can be adjusted to accomodate a LONG torso? I don't know my exact measurement, but I am for sure long between shoulder and hip.
