Stomvi Quad Case
Measuring 23” wide, 15” tall and 7.5” deep without music pouch, it features a hard polymer shell with foam interior, backpack and shoulder straps, a snap on/off music pouch, adjustable interior partitions, mouthpiece pouch, and 2 carrying handles.
It will fit 4 standard length trumpets or a combination of C, Bb, piccolo, and D/Eb. It can also be configured to hold one standard large trumpet, a flugelhorn with a bell diameter up to 6.6 inches and a piccolo trumpet in a rather compact safe hard shell case. It will fit in the overhead on large aircraft. On smaller aircraft it will most likely need to be gate checked.
