I opted for the Thomann Voyager Keyboard 3 gig bag as a lighter alternative to a traditional hard case, and I'm quite pleased with my choice. The bag itself is beautifully designed and offers substantial protection for my Yamaha SX900. However, I've noticed that when carrying the bag by hand, it hangs a bit too low to the ground, which becomes particularly challenging when navigating stairs. A slightly narrower design would elevate the bag higher off the ground, making stair climbing less cumbersome. Despite this, the bag’s lightweight design and overall quality still make it a very good choice for keyboard musicians.
