Mobility-minded, Reliable Protection When ProX deployed the ZeroG series of bags, they sought to meet the needs of modern DJs by blending security and mobility — Sweetwater’s pre-eminent beat jugglers agree that the company succeeded. Each bag has been painstakingly engineered to maximize protection without compromising portability, resulting in a backpack somewhere between a traditional, soft gig bag and a rigid, ATA-style hard case. Its thermoformed EVA exterior provides superlative resistance to the elements, ensuring protection from grime, liquids, and unwanted contact. Rigid aluminum zippers ensure each of the outer pockets stays securely fastened to keep your supplementary gear where you want it — ideal for laptops, cables, adapters, headphones, or any other accessories.
