         2 . The system of  claim 1  wherein the plurality of attachment rails comprise a T-beam cross section with a stem and the stem is connected to the first surface of the second back panel and the plurality of attachment rails are positioned to be accessible while the second back panel is attached to the first back panel. 
     
     
         3 . The system of  claim 2  wherein the modular backpack system further comprises a set of removable shoulder harness straps attached to the first back panel. 
     
     
         4 . The system of  claim 3  further comprising a removable waist strap attached to the second back panel. 
     
     
         5 . The system of  claim 4  further comprising a modular pack designed to attach to the attachment rails via a plurality of cam lock mechanisms. 
     
     
         6 . The system of  claim 1  wherein the second back panel further comprises a lumbar pad flexibly attached to a bottom edge of the second back panel and the lumbar pad can be moved relative to the second back panel to form an L-shape camp chair. 
     
     
         7 . The system of  claim 6  wherein the lumbar pad may be unfolded from the second back panel to form a substantially flat sleeping mat. 
     
     
         8 . A portable camp chair, the chair comprising:
 a back panel;   a seat pad flexibly coupled to the bottom edge of the back panel; and   a plurality of side support straps with a first end connected to the back panel and a second end connected to the seat pad and disposed to operate in tension to restrict the back panel and seat pad to substantially an L-shape while the camp chair is in use;   wherein the camp chair is configured to integrate into a wearable system when not in use.   
     
     
         9 . A modular backpack system, the system comprising:
 a first back panel;   a second back panel configured to be removably attached to the first back panel, the second back panel including a first surface such that the first surface of the second back panel is wider than the first back panel; and   an adjustable attachment system connected to the first surface of the second back panel including at least one attachment rail:   wherein the first back panel attaches to the second back panel by covering at least a portion of a center section of the first surface of the second back panel.   
     
     
         10 . The system of  claim 9  wherein the at least one attachment rail comprises a T-beam cross section with a stem and the stem is flexibly connected to the first surface of the second back panel. 
     
     
         11 . The system of  claim 10  wherein the at least one attachment rail comprises two attachment rails, and the two attachment rails are disposed along at least a portion of the vertical length of the second back panel in a substantially parallel configuration. 
     
     
         12 . The system of  claim 11  wherein the modular backpack system further comprises a set of removable shoulder harness straps attached to the first back panel. 
     
     
         13 . The system of  claim 12  further comprising a removable waist strap attached to the second back panel. 
     
     
         14 . The system of  claim 13  further comprising a modular pack designed to attach to the attachment rails via a plurality of cam lock mechanisms. 
     
     
         15 . The system of  claim 9  wherein the second back panel further comprises a lumbar pad flexibly attached to a bottom edge of the second back panel and the lumbar pad can be moved relative to the second back panel to form an L-shape camp chair. 
     
     
         16 . A modular backpack system, the system comprising:
 a first back panel configured and disposed adjacent to a user's back, the first back panel including a fastening flap; and   a second back panel configured to be removably inserted into to the fastening flap of the first back panel, the second back panel including a first surface such that the first surface of the second back panel is wider than the first back panel;   wherein the first back panel and the second back panel cover substantially the vertical length of the user's back when the second back panel is inserted into the fastening flap of the first back panel and the first back panel is worn by the user adjacent to the user's back;   wherein the second back panel is configured to be removed from the fastening flap of the first back panel, unfolded to a first position, and used separately as a camp chair in the first position and further configured to be unfolded to a second position and used separately as a sleeping pad.   
     
     
         17 . The modular backpack system of  claim 16  further comprising at least one module that is removably attached to the second back panel. 
     
     
         18 . The modular backpack system of  claim 17  wherein the at least one module is daypack.
