Mike Pelonzi and Joe Curran aren’t paranoid; they just have a few rules when it comes to their kids’ safety. No bike riding without a helmet. No boating without a life vest. And no going to school without a bulletproof backpack.

Only problem: the backpack didn’t seem to exist. So they invented My Child’s Pack, a bag with a back panel as bulletproof as a police vest that kids can use as a shield. It comes in four colors and costs $195. Since August, they have sold more than 1,000.
