My similar set up to @Monk with Hunter Element bags.

You can get various sized bags for the frame that just clip on. Thats just a half one there that can also be used as a big bum bag with shoulder straps without the frame. I have a 70 litre pack for it too which gives the same set up as Monk's but with a frame.
