black diamond 60l infinity, 1.7 kilos, extremely comfortable hip harnes that has a swivel joint that bears the weight allowing the belt to pivot, shoulder straps run as a loop under the swivel meaning straps automatically shorten and lengthen as your body posture changes from stride to stride.... holds as much weight as much heavier packs with ease..., ample outside stretchy pockets to hold extra gear..
have a 35 litre osprey pack as as well 1.3 kilos with a frame, again very comfortable. heaps of pockets for gear.
