What makes a good briefcase? Ask any suit with a 9-to-5 and a penchant for vicuña, and you’ll hear a few requirements: it should be lightweight, with a comfortable handle; large enough to carry a computer and some documents (the word “briefcase” is derived from the legal documents, or briefs, that lawyers carry), but not so bulky it looks like a weekender; and made of materials built to last so it can be passed on to the progeny. A slim messenger or duffel bag with a shoulder strap, but no handle — that isn’t a briefcase. It’s time to get serious about the things you carry. These briefcases cover the spectrum, from simple and affordable to luxuriously-detailed and expensive.
