Arachmid is an aramid fiber compound based on spidersilk. Not just any spidersilk. Silkworms living in an environment fed with H2O-vapor containing nano carbon tubes. These nano carbon tubes are absorbed by the silkworms via osmosis and are embedded in the silkstring being harvested. This material is lightweight and resistant to blades and projectiles. Does not protect against shock/trauma or blunt objects.
