Thomann Keyboard Bag 49-2

I purchased this to transport my audio technica midi keyboard, not worried too much about quality.

I found that it was of very good build compared to some other (very expensive) keyboard bags I have purchased. While I did buy for its original use, I have experimented with using it as a carrier bag for cables and other gear. My personal favourite fit for this bag was actually guitar pedals, It is of the perfect size for most pedal boards and has lots of room for extra accessories sch as cables and power supplies. My keyboard fits nice a snugg, fairly safe from any height drop, even room for my laptop in the front pocket.
Not seen in the picture but carrier handle is extremely secure.

I like to have cases for all my gear, and I tend to use 'soft' cases (as I no longer drive a van, and hard cases tend to damage the inside of cars!)
I was a little concerned about how well protected my keyboard would be in a soft case, but I was pleasantly surprised.
I'm not sure what is in the case, but it is reinforced by either (very) thick cardboard or possibly thin wood - especially around the edges. You obviously couldn't drop a solid case on top of it (layed flat) and expect the keyboard to survive, but the solid sides offer excellent protection; both in the car, and when putting down (or even dropping?) on the ground.
If you're clumsy, or (your roadie is) throwing all you gear in a van then you need a flight case. If you pack and carry your keyboard, then this a much more than a 'padded bag' and offers far more protection than you might expect. I'm really pleased with this one.
