The Healthy Back Bag tote features a patented, ergonomic design which feels lighter and more comfortable. By contouring to the natural shape of the body, the Healthy Back Bag tote hangs asymmetrically redistributing the weight through the length of thewhole back, not just from one point on the shoulder, thus reducing stress on the shoulders, neck and back.The Healthy Back Bag also features a highly organized interior which utilizes varied organizer pockets that are not only functional, but also provide optimum comfort when used properly. A contrasting silver lining makes it easy to see these pockets. This lightweight polyester microfiber has been bonded to a nylon knit backing for added durability. Each bag is treated to resist stains. Care Instructions: Spot clean only as needed with a damp cloth using distilled water. Mix a mild detergent with the water if needed. Use a lint free cloth to rub the area dry. Do not bleach, air dry only - no heat. DO NOT WASH.
