What are the characteristics of the Nomex CWU 27/P Flight Suits?

The Nomex® III and IIIA Frabic that make up these suits prevent flames from burning through for up to 10 seconds. The unique combination of fibers prevent build-up of static electricity that can cause additional risk of fire or explosion in certain situations. For cold temperatures, the flight coveralls provide an insulating effect. The solid brass zippers are highly durable, which expands the life of these flight coveralls beyond many other products.
