Very high quality bag material, will protect your nova system very well. Lots of pouches, I keep the following within at ease: A4 binder, pens, 3x guitar leads, nova system (of course) and a volume pedal. Great size.
The strap is quite thin although sits nicely on the shoulder, I found it to move around in the clip connected to the bag itself. The big flap on the outside is pointless. It gets in the way. I may cut if off!
