This moving rail system and detachable backpack's greatest assset is being able to tacke out stuff in the

backpack without actually taking the backpack off while hiking or working out,moreover,the top and bottom

may be used as separtely or attached depending on the volume. 

The survey results with backpackers showed that having to remove shoulder straps from the

shoulders and detach waist belt to pack objects,or to refasten the straps listed as the numbar 1 complaint.

The patented moving rail belt allowa for 180 degree rotation which makes it convenienient to take out

stuff by using the rail to slide the sack from the backside to the front
