I found moldable shoulder belts as well, less than 20 bucks shipped. Looking at adding the crampon case for tent storage. Thanks again for the tip!
I will be using it for packing in Shenandoah, lots of scout camping trips coming up. Probably carrying somewhere in the 35-40lb range. As the boys get older, they can carry more For now, they carry sleeping bag, pad, some clothes, and a portion of either the cook set, food, fuel or something of the like. My youngest is 7 but only weighs like 35lbs, so he can't carry much, but my pack mule older son (8) weighs around 70 lbs, time to start carrying his weight...
