HPG sends the stuff with each of their kit bags to buckle it to your pack straps when you have your pack on to take weight off your chest.It's almost a law of human nature to pack everything you can into your backpack, bino harness, etc, so if you go this route with a larger front pack, try not to put too much heavy stuff in it. You'll feel it in your back if you're putting a lot of miles on, as it pulls down from your front.
