Bull Pac's have been around for awhile now and I am a big fan of these frame packs. I have seen them in action this last year in Idaho and they are comfortable, tough and worth the money you will spend on them. Their website could be a little better but they probably spent all of the money on the development and quality of their equipment. They are also strong supporters of the Rocky Mountain Elk Foundation. Check out their link at: BullPac's Online.
