As long as it is specifically made for laptops, a messenger bag may indeed hold a laptop. The messenger bag provides fast and simple access and, in certain designs, may also function as a briefcase. A laptop may be stored safely and securely in a padded compartment found in many messenger bags. Make sure your laptop fits comfortably by checking the measurements of the laptop compartment. If you want to bring a laptop and other belongings with you, get a messenger bag that is large enough to accommodate them.
