Abstract: A sleeve pack for storing and shipping products comprises a body for containing said products having a top, a bottom and opposing sidewalls. The sidewalls of the body are generally flexible to provide an amount of give under a force applied thereto. A telescoping support bar is positioned in the body and spans between the opposing sidewalls for suspending products in the body. The support bar telescopes in length so that the sidewalls may flex inwardly and outwardly when force is applied thereto and further telescopes generally to its original length when the force is removed and the sidewalls return to their original shape. An embodiment of the invention utilizes a support bar mounting structure which functions as an edge rail protecting device.
