Last year I purchased the Kifaru Bikini frame,nomad bag, long hunter lid and grab-it and it's been a great pack. Expensive but the fit and comfort is great. I've used a bunch ofpacks before that for hauling meat;
2007-2009 -Eberlestock J34 -1 antelope, 1 WT doe, 2 muley bucks, 1 WT buck.
2009 -Eberlestock X2 – 1 Whitetail doe.
2010-2011 -Eberlestock Blue widow – 2 WT Bucks, 2 Antelope, 3 WT Does, 1 Muley Buck.
2012 - KuiuIcon 5000 2012 model – 1 antelope, 2 muley bucks, 2 WT does, 1 WT buck,
2013 - KuiuIcon 1850 bag (2012 frame and suspension) - bull elk, mule deer, 2-WT does.
