I have a Kifaru Reckoning and a MR Mule. The Kifaru is built like a tank. Great pack, possibly more than I need. It is certainly capable of carrying more than I am. The Mule has a much smaller bag, but a very easy to use load shelf. A waterproof 55-60l bag fits right in there. The Mule is a little nicer in day hunting mode. A little more compact and possibly a little lighter. I hauled out a small deboned Mule Deer buck and head and it felt really good. I’d lean Kifaru if you like to haul really heavy loads. My hip flexors and knees are screaming before the weight feels uncomfortable on my back or shoulders. Honestly I think both are fantastic packs.
