Stomvi Quad Case
Measuring 23” wide, 15” tall and 8.5” deep, it features a hard polymer shell with foam interior, backpack and shoulder straps, integrated music pouch (interior 15.5″X 12.5″X 0.5″), adjustable interior partitions, mouthpiece pouch, and 2 carrying handles. Empty, it weighs only 8 pounds.
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.
