A wearable carrying system for a container such as a backpack or a bag has one or two straps that extend over the shoulder(s) and torso of a user. The strap or straps include a bladder system that is sequentially inflated or deflated by the controllable introduction and removal of a fluid into and out of the bladder system. A shoulder pad is located on a portion of the strap, the shoulder pad having an additional controllable bladder system to adjust the load bearing position of a strap on the shoulder of a user.
