There is now an extreme way for students to protect themselves in the unfortunate possibility of a school shooting.

A bulletproof backpack is now available in Austin.

"There's not a handgun round that will go through here -- this is the highest rating that there is," said Kerry Clark, creator of the "BackPackShield."

The BackPackShield is 12 layers of Kevlar topped with layers of polymer, making it bullet resistant. Clark created this shield for his high school daughter and other students.

"At least every year I hear of a kid at her high school, involved with her school, that has brought a hand gun to school," Clark said.

Clark didn't want to stand by without doing something to protect the students at school. He developed the BackPackShield in just a few months. He tested the shield in his underground, concrete bunker.

One shot from a .40 caliber standard police "Glock" was fired into the product, but when you look up close at the shield afterward, there are no holes -- just indentions from the impact.

"This particular shield has been hit over 40 times with high velocity rounds and on the back side there's not a single hole in it," Clark said.

The BackPackShield is virtually resistant to every handgun. Clark has tested it with all of level three 'A' bullets, and yet some parents and students say it might not be enough.

"A backpack is just covering the back of your back so you still have the rest of your body exposed," said Meredith Stoner, college student.

"I would feel better, why not? But at the same time it's a 50-50 chance," said Amy Resi, concerned aunt.

"There's no perfect situation in life -- you can't think you're never gonna get struck by lightning or injured," Clark said. "It's just like a seatbelt on a car. I wanted to give them something as a survival edge."

The shield insert is designed to fit into standard sized backpacks. Clark says it's intended to be used as a shield to hide behind should gunfire happen on campus.
