Thomann Fibertech Trombone Green

I recently bought this case for my King 3BF which is on the smaller side. The velcro strap that secures the horn inside the case is probably designed for bigger trombones, but after adding an extra set of self-adhesive velcro strips (3€ at a fabric store), it fits super nice and snug!
The trombone compartment itself is also long enough to fit my horn even with the tuning slide way out, something the original case did not.

The lidded accessory compartments are pretty spacious, but the one closest to the tuning slide section is just a little too shallow to fit my (Bach 5G) mouthpiece. Not that it matters, as the other compartment is much deeper and can fit several mouthpieces and maintenance products without any problems.

Other than that, the case is super light, easy to carry and has a very comfortable handle. The color is very vibrant, but it doesn't take too much to make small scuff marks in the lacquer.
As for protective qualities, I haven't used the case for very long, but it has already protected my horn from any damage when I tripped while carrying it.

All in all a great case for anyone looking for something a little lighter or more ergonomical, while still wanting to keep their horn safe.

Muy resistente para los viajes en los que el trombón puede sufrir.

Pros: Los materiales son duros pero a la vez no es un estuche pesado. Como mochila es muy cómodo y de estética es muy bonito.

Contras: En un Primer momento con mi trombón schagerl TP-450 la válvula de cuarta y el velcro para sujetar, no llega ha cerrarse bien. y al cerrar el estuche hay que forzarlo un poco. Con el tiempo espero que coja forma, y si veo que sigue quedando apretado le quitaré el velcro. he probado con otro trombón con sistema cerrado y encaja bien.

Posibles mejoras: que el velcro de sujeción fuera de quita y pon estaría bien, y echo de menos un bolsillo exterior.
