RE: What size pack do you use on a backpack hunt?
I use a Alsakan pack from cabela's,it can hold everything I use even my lightweight wool pants when it snow's in September,I freeze my butt off.
I've seen it snow at least once in every month at sometime in my life,in September(September 12 th)I've seen 6 inches of snow on the ground.
I carry a light weight -10 degree sleeping bag,I can always unzip the side if I'm to warm.
