Settlers rode horses & used packs.

The Settlers Sack

 Worn four ways.  Backpack - Messenger across body - lower shoulder - high shoulder

(my only wish here was that i was not in such a rush to show off my new shirt.  Where if I wasn't I could have removed the tag) dope. (and I would not have worn it with this bag.  This bag is better of with solid colors.)  

This primitive design can be found here.
A matching Hipshack is on its way.
