The duffel bag, crafted from green RPET fabric (made from recycled plastic bottles), is lightweight, water-resistant, and durable. Innovatively, the front panel and both sides adopt EVA one-piece molding technology to create a sturdy, pressure-resistant 3D structure for enhanced item protection. Features like the rear zippered document pocket, high-density padded handles, triple-layer cushioning at the base, and a scientifically organized compartment design optimize usability. The bag achieves a unified balance of lightweight construction, robust protection, and an exceptional user experience.
