Review on Eberlestock Mainframe Pack: Optimized Backpacks and Versatile Daypacks by Dan Bobbert

Very good backpack for a hard day of hunting. We packed an adult bull in a harsh upland area with lots of downy forests. It was a hunt that pushed us both physically and mentally. This backpack is lightweight, durable and easily adjustable. Holds the load as well as you can tighten it, meaning if it comes loose it's not the packaging's fault. Fatigue and discomfort were extreme during the 12-mile day off-road and the last 3 miles exhausted the bull. When you work that hard, you can appreciate a good frame backpack. A few weeks earlier we had packed another adult bull and I was using my mate's old Alaskan pack which worked well with thin padding. This pack was painful even in relatively easy terrain, although it was still at 10000+.
