A back strap for carrying objects, such as books, includes a base upon which the objects are placed. A first shoulder strap defines a handle at one end thereof, and extends through aligned apertures of the base to form a loop over a base. A second should strap, defining a handle at one end thereof, similarly extends through aligned apertures of the base to form another loop over the base. A side strap extends from one side of the base to the opposite side of the base, generally transverse to the first and second shoulder straps, to form a loop over the base. Adjustment mechanisms associated with the first and second shoulder strap and side strap allow for the adjusting of the length of the loops over the base to securely tighten objects onto the base for transport.
