I tried several packs out last year for backpack hunting and ended up liking my Gregory Whitney the best. I have the Cabelas pack and its ok but you give up so much weight on the front end that it just didn't seem worth it. It has lots of cool compartments and the gun carrier was nice but the belt wouldn't sinch down small enough to move an adequate amount of weight from my shoulders to hips and that thing wore me out. If you need a frame Kelty came out with a great little pack frame that weighs almost nothing and I lash it to the outside of my pack. The two are still much lighter than the cabelas guide series pack.
I love cabelas products and satisfaction guarantee but in this case it wasn't the pack for me.
