I have a few different backpacks and a lumbar pack (Sitka tool belt), and I’m curious what the benefit of the lumbar actually is? I’m just a whitetail hunter who doesn’t pack out deer, but I don’t see the benefit of a lumbar pack. If folks want something lighter why wouldn’t you want a small backpack? I think a pack is more comfort to carry, and with the lumbar packs you generally still have the shoulder straps, if not they are miserable. I do like the layout of the tool belt and use it time to time but once again, I don’t see the true benefit of one.
