We love this new bag for its quirky teardrop shape, but it has a far more useful reason for its shape that just looking cool. A doctor and chiropractor teamed up to develop the bag, which curves with the spine to make heavy loads seem lighter. Weight is also distributed asymmetrically along its whole length so it doesn’t put strain on any one place. We’ve tried the bag out, and it’s ideal as hand luggage or travel day bag.
