The Peak Performance Violin Cases feature incredibly shock-absorbing and insulating resin foam shells with features that make carrying your violin convenient. Large exterior pockets, incredibly comfortable backpack straps and back cushion, and even a bam water bottle make this case ideal for violinists who need their case to move as fast as they do. This Compact version (4/4 only) features a shorter case with the bam external bow tube for easier airline carry-on and lighter weight. The standard oblong 4/4 Bam Peak Case features 4 internal bow holders, while the 1/2-3/4 size Peak Case features only one internal bow holder.
