The WolfPak Double Trumpet Case has been designed to offer the superior protection of a hard case while providing the lightweight convenience of a gig bag. WolfPak Trumpet Cases feature a shatterproof shell to eliminate weak points associated with normal closure hardware plus over 1-1/2" of fabric-covered foam to absorb any blows to the case from normal day-to-day use and abuse. Because of their revolutionary design, WolfPak Trumpet Cases outperform other conventional wood or fiberglass instrument cases..
