A quick release modular backpack system for rapidly shedding load components generally incorporates an essential load support constructed to be releasably secured to a support surface, such as a person's torso, and further incorporates an auxiliary load bearing module and a quick release mechanism having a first position releasably coupling the auxiliary load module to the essential load support with an actuator constructed to shift the quick release mechanism into a second position with a single motion to completely shed the auxiliary load module from the essential load support while the essential load support is retained on the support surface.
