I have an Ol Man climber...I wear the climber on my back and strap the backpack to the climber...

I have my climber strapped to me and the backpack strapped to the climber. It's how I pack in stuff now...it's the easiest way.

Actually, now that I think about it, I've worn my climber in on my back...and stuck my backpack on me but done the "pregnant lady" approace, with the stand on my back and the pack on my stomach. That'll work too...though it's awkward.
