Master-Piece was built on a commitment to high quality and functional design, and their 3-Way Brief Case is a testament to this. Made from 600D polyester the fabric has been treated to a PU coating resulting in a fabric that is both durable and water resilient. The backpack is equipped with the brand's "m-strap" mechanism which reduces the load on the body, allowing for a more comfortable wear. With a 14 inch laptop pocket, this bag has been designed to function as either a backback, shoulder bag, or briefcase, for whatever your travel needs.
