Once upon a time, you might have scoffed at the idea of a lady backpack. A purse was considered more stylish—or so the fashion magazines had told you—and modern. But then, over the years, your priorities shifted. Not only do you now need more space to carry your own wallet, phone and other must-haves, but also snacks, backup clothes and other must-haves for your kids. Maybe you want to throw a laptop in there, too. And if your back is not as strong as it once was, the appeal of the backpack—and the way your posture immediately improves whenever you wear a balanced one—becomes increasingly undeniable. Added bonus: enjoying the convenience of being hands-free and not having to worry about dropping your phone.
