I have been on a search for the perfect day pack, rarely it may be called on to haul meat but no loads too heavy. I'm a tinkerer by nature and have really gotten enamored with the idea of putting a pack together with a 1606/FILBE frame.
That said I can't find much detail of what it would take to for an HPG harness, Prairie belt, then a bag of some sort with a Tara bag for compression. Overall I'd like to end up around 2500ci.
I know there are references to using HPG great for the harness and belt but I came find much info as to how involved that process is. Also difficult to find is exactly what bags for the best on this particular frame.
