Lugging around my
Inspire 2 is not comfortable or practical for me. That’s why I bought the Mavic 2 Pro!! It can do (almost) the same things as my
Inspire 2 and NOT break my back trying to carry it around. I only use mine when I’m able to use my Drone Crates landing mode case and that way I can simply roll it out to my current location and setup.
I have looked at Lowepro’s backpacks and they look like a viable alternative for hiking with the
Inspire 2 at a reasonable price. You might want to take a look at what they have to offer?? You should realize that you’re going to be carrying a lot of weight on your back with all the various equipment that you will need to be able to get more than a few minutes of flying. Batteries, lenses, cameras, etc add a lot of weight.
Mine came with a carrying strap contraption almost like the one you showed for the original travel mode case but it’s so uncomfortable and hard to wear that I’ve never used it.
