Not the most practical thing to own... but some REALLY cool fashion and design went into the production of these things.
Quote : If you like post apocalyptic fashion mixed with high end runway then you will love these diamond studded gas masks. No need to wait for the mushroom clouds to start a revolution. The masks were the creation of designer Diddo Velema, with Gucci and Luis Vuitton.
Not something likely to rely on for protection from the harsh wateland.. but pretty damn cool if you ask me... Check it out!
