The piece is made with a PU leather exterior, a material chosen for its smooth, durable surface that holds the structured square shape and chain hobo silhouette. The exterior is further described as polyurethane synthetic leather, giving the body a soft, foldable handfeel that suits the relaxed, retro-inspired commuter look and everyday styling. Inside, the lining is polyester, providing a smooth interior layer for the main compartment and the zip pocket.
