Thread: What size backpack for multi-day hunts?

Ok, so I'm looking for a multi-day backpack.

I always tend to go for too small so as a kneejerk reaction I'm looking at Osprey Aether 85l (and furtively at Stone Glacier Talus 6900, but I don't look too long in case I press the trigger.)

For those who know: what is a good size for a multi-day hunt backpack?

Probably needs to include lightweight tent for those times you want/need one. I figure you can always carry less in a big bag, but you can't carry more in a small one.
