I purchased 2 of the Commander X pack frames in 2018 for hauling out moose. One for myself, and one for the other guide that works with me. The outfitter that I own packs out several moose each fall. Over the last 3 seasons we have used it to haul out 7 moose all weighing between 800-1000 lbs dressed. Each pack has held up extremely well, I am beyond impressed. There is not a single rip or tear.
I would mostly recommend these packs for game sized species of elk, deer, etc. I wouldn't purchase them again for moose only because the weight sits too low on your back even after adjusting the straps. If you are looking to pack out large game, I would recommend something with a shelf that keeps the animal up towards your mid-upper back.
I can't say enough for the quality of the product so far though. I have been extremely happy.
