This is a lightweight, fabric saxophone bag with a thick cushion (about 3 cm thick). It offers sufficient protection, but it's not suitable for situations like crowded trains or being tossed around in the back of a truck. It's best suited for carrying by hand and placing at your feet in the passenger seat. It comes with a shoulder strap. It does not convert into a backpack. Please comment if you have any questions. As shown in the third photo, the leather on the handle has deteriorated and has cracks, but I don't think it will tear.
