This archery season I began solo bevy hunting. I've been in crazy rough terrain so lightweight was a necessity. I used a Sitka 32 liter. I was able to carry two nights worth of stuff easily and for sure could do more. That includes 100 oz of water and I would strap on my bow. As the weather gets more winter like I think I would need a bigger pack as my 18 oz sleeping bag that stuffs to the size of a large grapefruit would be inadequate and I would certainly need more warm weather clothing. I did however learn that making do with a smaller pack forces you to go light and I definitely like that all day long. Not as much at night but oh well. There is always trade offs.
