Had about 70lbs of elk meat on mine today, with a 10lb rifle strapped into the water bottle pocket.
We were 2 miles in and 1000 ft up.
This is by far the best pack I have owned. Comfortable and feather light going up,and very comfy loaded up for the hike out.
After today my hunting partner will be buying a Paradox. He struggled with a similar load and was in pain for the last mile or so.
I cannot emphasize enough how happy I am with this piece of kit, and I tell everyone that will listen.
