No matter what you're lugging around, the FlexVent injection-molded shoulder straps have got your back (and shoulders). So much so that the American Chiropractic Association endorses it. Sturdy and stylish, this backpack is a must-have for your on-the-go lifestyle. So, if you ever find yourself needing another The North Face daypack, it won't be a question of "Should I get the Borealis?" but "What color should I get?".
