New drum roto mold case sets are a major breakthrough in the percussion world for Gator. The exterior shells are rotational molded of high-density military grade polyethylene with a very durable finish. The straps are permanently fastened to the shell to make assembly easy after the gig and prevent strap loss, which is common with some of the competition. All of the Gator Drum Cases are lined with high-density closed cell foam covered in rugged tricot, which is then glued and riveted to the shell. The riveting process is extremely important to the durability of the Gator Drum Case, since the competition only glues the lining in place, which easily detaches making long term usage extremely difficult for the drummer. The unique male/female top and bottom design allows for easy stacking and locking together for transportation.
