The Ahead Armor Bass Drum Case features a unique teardrop and patented TruForm™ design. This innovative design corresponds to the ''true'' shape of the drum plus its mounting hardware and the universal teardrop shape allows a much snugger fit. Complete with a DynaZip™ zipping system and DX-Core™ construction, the Ahead Armor case provides superior protection. The plush interior is complemented by the strength and durability of a weather resistant and waterproof, 600 denier polyester exterior with a double stitch for added strength.
