SALT LAKE CITY -- In the aftermath of the deadly elementary school shooting, demand for a Utah company's bulletproof backpacks is skyrocketing.

They're lined with a light material that can stop bullets. The company said it used to only sell a small amount of children's body armor and backpacks at gun shows, but ever since the Sandy Hook shooting, sales are on the rise with people looking for ways to protect their children.

"The concept came up as things happened at schools; children need protection as well,” said Rich Brand. “Anyone who's sending out a child into the world, seeing what can happen now, they want to protect their children."

The backpacks retail from $150-$300. The company said its seen a worldwide demand for its products, including child-sized body armor and their website has crashed several times.
