Sam, apparently you take the bears size in feet (squared) and square it to he the approx weight of the hide. 8ft bear weighs approx 65, 9ft 80, etc. mine was 8.25-8.5 squared so about 70lbs for me. I had about 20-25 in my pack before so I packed out about 90-95lbs. Guide took the skull which weighs about 10-12 lbs.
