The Gator Cases Standard GP-2418BD Bass Drum Protector Bag (24x18") is another well-designed Gator bag designed to guard your drum against bumps and abrasions during transport or storage. The 10mm interior padding provides a soft cushion that gently surrounds the drum finish. The soft exterior of the Standard Series is a water-resistant nylon that is rugged and fabricated to withstand the rigors of the life of a drummer. Comfortable carry straps make toting it around easy. When not in use, the bag collapses for temporary storage during your performance.
