Sure most of us don't need a bullet proof suit but it sure sound very James Bond-esque. Garrison Bespoke uses a special carbon nanotube material so that the suits are flexible and normal. The minute a bullet makes contact with the material, it hardens to protect the principal wearing this magical clothing.
The material is 50% lighter than Kevlar (the traditional bullet proof material) and was tested to stop .22 and .40 caliber bullets. Before you run out to buy one, its important to remember that this wondrous tech costs about $US20,000 but I'm sure the intended customers can easily afford this additional layer of protection.
