Biotechnica "Smart" Gas mask

Most gas masks are stuffy, hot, and hard to see out of. Biotechnica's "Smart" mask is none of these. IVs a lightweight, transparent, form-fitting mask that allows the wearer to breathe and perspire normally while protecting him from deadly gases.

The mask resembles a clear stocking mask, put on over the head. Its secret is in its materials—the substance of the mask is a reactive bioplastic that allows gases in and out Whenever harmful gases are going to be drawn in, the inner molecular make-up of the mask prevents the gas particles from going through, trapping them in a protective outer membrane. Based on human biochemistry (particularly blood and digestive systems), the mask is nearly 100% effective against airborne and contact toxins. (It only protects the head and upper neck against contact toxins; for more complete protection, an environment suit is needed.) Because of the toxins trapped in the mask, it must be discarded for safety within twenty-four hours of encountering toxins.

Of course, the mask also stops airborne particles such as pollen, dust, and most pollution! The "Smart" mask was developed from a commercial version that won't stop the super-small globules of nerve toxins, but stops anything larger (which means anything but nerve toxins, including CS and tear gas). This commercial version lasts for twelve hours of use and retails for 5eb.

Please note that a "Smart" mask won't allow you to breathe in completely hostile atmospheres, where there's not enough oxygen to survive.
