not sure there is an all purpose pack that fits every need but there are many that are pretty versatile.
stone glacier , kifaru, exo, mystery ranch, eberlestock are all worth looking at . I know I'm leaving some out , there are many more , just depends what you want to pay.
IMHO , eberlestock is a decent pack but not in the class of others I mentioned . but they are also cheaper and are well made . they did not seem to fit me well and just felt uncomfortable to me compared to the others . but I do know many who love them, so ,give em a look.
I have the exo 3500 WITH K2 frame. it' s good for a 3-5 day trip. longer stays ,it's probably a bit small ,cause it does fill up fast.
it will however compress and make a pretty decent day pack, once you set up camp and drop most items you need for camp.
I didn't but would probably recommend going with the EXO5500 over the 3500 if you plan on staying several nights . it will still compress down to where you notice virtually zero difference between the two ,when empty . either one you can drop the bag completely (or not ) when hauling meat.
now exo has a whole new line in their k3 bags and frames .
very much recommend you check them out if interested in a high end pack system.
