The exterior is made of 16-ounce heavy-duty canvas, treated with a stone-wash process to achieve a natural texture. It features a printed cotton lining and an interlayer of EPE (expanded polyethylene) foam for cushioning. The shoulder straps are a combination of canvas and leather, stitched with waxed thread. The opening is secured by a two-way zipper with antique-bronze metal pull tabs. Ventilation holes lined with metal mesh are positioned on the sides. The base includes a removable, rigid insert board.
