Lighten your loads with the first ever weight-reducing backpack that sports suspension like that of a race car. The zany Zero-G Weight-Reducing Backpack is a real spine-saver, its clever weight-dispersion mechanism system backed by a 100% scratch- and waterproof construction which features 12 unique storage spaces. Don’t take our word for it, lab tests have proven this will effectively reduce up to a quarter of its carried load.
