Engineered for the demands of mobile DJs, musicians, and audio professionals, the Thump15A/BST Rolling Bag is constructed from rugged 600D polyester fabric with a water-resistant polyurethane coating to protect the speaker from wear, tear, dust, and moisture. For impact protection, the interior is padded with foam and features stiff polyethylene boards on the bottom and sides. The bag's key features for mobility are its integrated wheels and a retractable handle, allowing you to roll the heavy speaker with ease and avoid the strain of carrying it. For accessories, an exterior pouch with a hook-and-loop closure provides a convenient storage spot for cables and other small gear. Heavy-duty zippers ensure the bag stays securely closed, and comfortable webbing side handles are available for lifting.
