Thanks for the tips! Unfortunately, the way the shoulder straps are built and attach, this wouldn't line up well and work for load lifters. I've got some Ideas I'll tinker with at some point.
I have plenty of webbing and plastic hardware from all my projects, so I put together a couple straps to secure deer and gear.
Check out the video for a quick view of how I'll be packing them out. I may make some dedicated vertical straps, but I'm not sure it's necessary, as the leg straps work so great for this.
