HPG forum says 5 lbs and 3500 ci. I would think it would be on the high side of 5lb looking at the construction.
that was balanced atop a postal scale. got the same result 5 times in a row.
ETA: Hands down, my best heavy load carrier right now is a Dana external with an HPG Prairie Belt and a little bit of magic performed in the lumbar area. You've got to get above at least 50 pounds to start observing how good it is in comparison to other options, and it doesn't really pull ahead of a properly set up internal until you top 70 or so pounds. If I can match the load carrying capacity of the Dana external with my design, I'll be satisfied. If I can exceed it, I'll be very happy. Either way, my design is more versatile and readily configurable than the Dana offering.
