I have a popup and a Kifaru setup. I prefer the
popup because it’s about 2lbs lighter.
I use the Kifaru if I intend to pack in camp for more than 3 days, know I’ll be carrying more than 40lbs, and it stays in truck or on bike or in camp to haul second and third loads.
So far, I hunt with the popup. If I kill, I load up to 60lbs in it and pack out. I’ll grab empty Kifaru to head back in for a second load, as if I’m pushing over That weight id prefer the beefier frame.
the Kifaru is bullet proof. But honestly if I were starting over and only doing one, and Day hunting in lower 48, I’d go for one of the pack brands that’s lighter but handles heavy weights still. They aren’t built as tough as Kifaru, but are just as comfortable, and if you bust one, you’re usually not in too bad of shape. If I were backcountry hunting, or north of border or in Alaska, I’d want the brick house pack - your life may depend on it.
