    Abstract: A protective garment of the type typically worn by fire fighters with improved water resistance is disclosed. In particular, the present invention is directed to an outer shell material for protective garments that is made from a fire resistant material coated with a durable water resistant coating. The durable water resistant coating is applied to the outer shell in a manner so that the coating will not degrade when exposed to normal wear and tear and even after the garment has been laundered repeatedly. Protective garments constructed in the past typically lost most of their water repellency after being laundered as little as five cycles. It has been discovered that water resistant coatings applied according to the process of the present invention, on the other hand, can survive at least 30 laundry cycles, and in many applications at least 50 laundry cycles without significantly degrading.
