Bottega Veneta - Bottega Veneta's black Hidrology briefcase is recognisable by the Intrecciato leather-weaving technique - such an applied specialism that the house opened its own La Scuola dei Maestri Pellettieri in 2006, to hone new generations of craftspeople. It is shaped to a streamlined, supple silhouette that's water-repellent to give your tech ample protection. Use the rounded top handles or attach the long strap to carry across the body.
