This Bulletproof Backpack, looks like normal backpack. When facing danger, just pull out the shield by using its handle and put it across your chest. What looks like a “normal” backpack will then become a bulletproof vest for your emergency protection. After minimal practice of pulling out the shield, you will begin to complete the whole backpack to bulletproof vest transformation in about 1 SECOND!
You dont have to worry about protection for your back as it is protected by another piece of bulletproof shield.
