Humm, there are guys MUCH more knowledgeable than me with much more experience with different packs....
....so naturally I'm going to chime in. From what you've posted, It seems you just need a daypack. I have experience with an Eberlestock X-1 which would fit that profile. I like mine, it's built like a tank, can pack a day or two camp, certainly all gear for a day hunt and it can haul out meat. It's around $179 or so. It is sort of "hunting pack" specific considering the built in scabbard. If you aren't using it for hunting this would be and unnecessary feature.
But there are lighter weight alternatives that are well made if just a daypack is all you need. Some of the HillPeopleGearhttp://www.hillpeoplegear.com/
packs are highly touted around here. The Tarahumara seems to be particularly well liked.
