When it's above freezing, my pack weighs 8.5-9 pounds including clothing worn/shoes. That doesn't include food/water/gun.
Including the clothes on your back and your shoes... Really? For a backpack hunt?
Sleeping in the dirt with no bag or shelter, huh?
I think my first solo bp hunt I was a little over 50 lbs. Like others have mentioned, you quickly learn what is necessary and what can be left at home!
