Airbag Backpack
It won't help you in a crash, but you should still strap on one of these Airbag Backpacks ($300). Made of exploded airbags along with truck tarps and old seat belts, the waterproof bag features compression straps to shrink or expand the main compartment, and has a buckle to keep rippling down to a minimum. It's also made from 99 percent recycled material, so you can feel a little better burning up those dinosaur bones. [via]
