Very well made and very well designed. I use it for my Bb trumpet, cornet and Flugelhorn. The music pocket on the side is so generously proportioned it could easily accommodate 3 copies of Arban! Lots of pockets for pens, valve oil etc The large end pocket is large enough for a Hercules mute holder and the detachable mute bag will take half a dozen mutes. One word of caution - although it is well padded it is not a replacement for a hard case.
