The Guard Dog ProShield 2 backpack comes from the leading manufacturer of security, self-defense and tactical products. Measuring 19 inches in height, this bulletproof backpack is ideal for youth, college students, travelers and professionals alike. Protected with lightweight armor, the backpack weighs only ounces more than a non-protected backpack. The ProShield 2 comes with enhanced comfort padding, allowing you to wear the backpack with ease, supporting heavy loads with added padding on your back and shoulders. Also there are several organizational compartments, a tablet/laptop holder and auxiliary cord connection so you can listen to music directly from inside your backpack or use hands-free headphones.
