Even if your journey to the office these days is from your bed to the kitchen table, a briefcase can help you get into the work mindset. (Though for now you may just use it to store your laptop when it’s time to eat.) If you’re traveling to an office, a briefcase is a stylish, professional way to carry your stuff. (For heavy loads, however, it won’t be as ergonomically friendly as a backpack or messenger bag.) We’ve tested 25 briefcases over the past three years—loading them up and then walking, running, commuting, biking, and flying with them. These six should work for many different carrying needs, looks, and budgets.
