Designed for kids ages 8 and up, the iSafe backpack has a built in security system, which is powered by batteries and can be activated by the wearer pulling on a cord. Once the cord is pulled, the bag sounds off as loud as a car alarm and can run up to 2 continuous hours on a fresh set of batteries. The alarm system only adds about .5 lbs to the backpack, which is available in boys and girls styles for $59.99.
