Goretex is an American company renowned for the manufacture of water proof fabrics.
They have also added a modacrylic fibre to their product to produce a flame retardant fabric for use in outer garments.
This fabric has been tested to ISO 811 (for waterproofness), EN533, EN531, EN1149 and ENV50354.
It has only passed class 1 arc in a box test, so it should only be worn over other arc tested garments if it is used for protection against electric arcs.
As the fabrics are antistatic, they are ideal for outer clothing for working in hazardous environments.
