heres what i can tell you...i have had my pack for over 20yrs now, got it when i was 18. i've beat the thing to death....scouting excursions, canoe trips, packing out game in it ect. after 20yrs of hard wear and tear it needed some "patch work". took it to the factory where the hard working folks make these things by hand. told em it was my favorite pack. that the thing has seen more miles than some marathon runners. they patched it up for free with a smile on their face. they knew it was more than just a pack to me. they took pride in that too. perhaps a bit spendy, but again, you cant buy that kind of service.
