The shaped BAM high-tech case DEF2200XLA of the La Défense series for viola combines a particularly compact shape with the advantages of the innovative high-tech material from BAM and the modern design of the outer casing in an aluminum look. The outer shell of the viola case consists of the patented high-tech BAM system, a 3-layer structure made of particularly durable materials. This makes the violin case particularly light (only 1.9 kg!) and stable.
