Abstract: A carrying bag includes a first outer surface, a first compartment, and a ball compartment. The ball compartment is separate from the first compartment and is configured to receive and hold a sports ball. The ball compartment is adopted to conform to the shape of the sports ball and to define a first portion of the first outer surface to have a shape of about a half of the sports ball.

Abstract: The present carrying bag is comprised of a primary container with a primary opening which is closed with a primary zipper for receiving personal items, such as books. Primary straps are attached to the front of the primary container. A ball container is detachably connected to the back of the primary container with a connecting zipper along the periphery of the ball container and on the back of the primary container. The ball container is comprised of a basketball basket for clearly indicating that it is a place to put in a basketball. The ball container is maintained in its shape by a first rib in a rim of the basket, and second ribs in a conical panel of the basket. A lid attached to the top of the ball container is detachably connected to the rim of the basket by a rim zipper. Divided compartments are thus provided for the ball and personal items to provide enough room for them and to prevent them from mixing. The ball container may be detached from the primary container by unzipping the connecting zipper.
