I also have had a moroka pack but it was almost 4kg empty the exo is just over 2 and I like the compartment between the bag and frame I will often cut the neck of fallow deer and put them in that section of stops antler and cape slipping about when walking out.. the red pack in the first image is a torre by macpac it was the original internal frame pack after the mountain mule days with the external frame.. I’d agree with gryphon that the moroka packs are very well made and have good adjustments to suit you personal fit
