Good budget bag

It's a strong bag with well attached strap-handles. It has no padding internally so you would need to add foam etc to secure and protect your keyboard. In my case, it was the closest I could get size-wise but my keyboard is still too small for it really.

For a budget bag to carry keyboards (or any equipment for that matter) in, it is good quality and I expect it to last for years. However - it is just a shaped bag with zips and handles. It provides no protection other than from dust and maybe a light rain shower.
