I have been looking at the horn hunter main beam packs and am stuck between the main beam or main beam xl. the dilemma being is the main beam too small to fit items such as jackets or sleeping bags for a 1-2 day hunt at 2800 ci. I like the XL at 4000 ci but I haven't been able to get a clear answer on if the XL has side water bottle compartments. anyone out there have the answer? or better yet, does anyone have pictures of either packs in use???
