The piece is crafted in PU leather, a smooth and finely textured material with a soft, waxed finish that gives it a rich retro sheen. Its breathable, flexible nature holds the relaxed hobo silhouette with a firm yet supple handfeel, while the sturdy surface resists wear for everyday use. The medium-soft structure keeps the piece comfortable under the arm, and the PU leather suits the American retro aesthetic and the casual, everyday occasions the piece is made for. Inside, the lining is made of polyester, a secondary interior detail that supports the zip closure and the slip and zip pockets within. The strap is also made of faux leather, with two detachable straps and a removable handle, and the hardware is zinc alloy.
