It is that time of the year again to buy new gear for the upcoming elk hunt. Every year I want a new backpack, but never find one that fits my needs. What do you guys recommend for a backpack that you can live out of for a week in the mountains? I have looked at several, and I am never fully satisfied. Usually they are too heavy. The latest one I am looking at is the Cabelas extreme light series. It is a 5000 in3 pack that weighs about 4 pounds. The pack in the store says 4 pounds, the website says over 6. So there may be another shot down. Any ideas? What size do you guys use? My current one is 7200 in3, but that is huge.
