There are few better ways to make a jacket more sportive than adding patch pockets instead of flapped pockets. Pockets were added to garments in the 1600s and were, of course, practical in nature. From money to keys to jewelry, pockets were made to hold valuables and everyday items. Flapped pockets were more secure for suit jackets and sport coats as the flap protected those items. Patch pockets, however, added a cachet to the garment. They weren't as secure and thus a bit more dangerous. They said something about the wearer. The easy access, the more frequent use, the shape...patch pockets are the sports car of pockets. More efficient and more rakish. Quicker and, frankly, better looking. Sportive pockets for sport coats, we say.
