Evatek Softcase backpack bag for handpans up to 58 cm diameter. The backpack has a larger pocket (for eg two water bottles and sweater / jacket) and a smaller pocket for keys or small change (on the hip belt). With hip and chest strap for better wearing comfort.
Another plus of this bag is that it stays horizontal and does not tip over when you put it down.
