Adjustable shoulder strap with leather trim. Either Thick black cotton or Italian linen webbing with leather trim to match the laptop case. This is the best option for the goatskin laptop cases, as the goat skins are not large enough for cross-body straps.  Handstitched "f" on the leather trim.
Two options:

No. 1: Fastens with press studs (In the navy photo). This is the best option when ordering a laptop case with any ceramic hardware, as the snap hooks can damage the ceramic finish on the rings over time.  Hardware options are matte black, gunmetal and nickel.

No. 2: Fastens with snap hooks (In the tan leather trim photo). Hardware options are gunmetal or nickel.
