This Ahead Armor Cajon Deluxe with Backpack Straps measures 21x12x12, and is packed with innovative, yet practical features. The ARCAJ1 is constructed from a heavy-duty, waterproof, 600 denier polyester exterior. The interior has two layers of high-impact foam padding and a soft lining of premium Sherpa Fleece. These resilient cases from Ahead have been practically designed to hold not just the drum, but the mounted hardware as well! Ahead Armor Cases make it super-easy to get your drum in and out of its case, thanks to their 'Dynazip' zipper, and their cutaway design eliminate tight squeezes and vacuum effects. We carry these heavy-duty, rugged drum cases in all sizes at the Drum Center of Portsmouth.
