Leather briefcases are the oldest type of business bag and the classic style with their buckles, and practical interior compartments has stood the test of time, making them a timeless addition to any working-man’s wardrobe. But thankfully, modern-day styles have evolved a great deal since the days of our father’s boxy, sharp-cornered case. But the type of business bags carried by today’s trendy business men and women require a hint of uptown sophistication and a more modern approach to the traditional style. Hence classic styles are often replaced by backpacks, tote bags, satchels and messenger bags. These bags are all an ideal, acceptable alternative for business and college use, especially for those of you who want a more laid back, but professional look.
