The current flight suit that is standard for most air forces and navies is made of Nomex, a fabric made from spun aramid that is lightweight and fire-resistant. The flame-retardant capabilities of this material make it ideal for protecting aviators in case of a fire. The suit is often green or desert tan in color, with multiple pockets for specific pieces of gear (such as a clear plastic pocket on the thigh intended to house a map of the aircraft's planned flight path), but color, style, and cut vary greatly from country to country. The current model flight suit for the US military is the CWU 27/P and is available in sage green and desert tan. Commercial flight suits for civilian flying are also available, and are frequently used by helicopter crew (including non-pilots such as flight engineers, paramedics, and nurses), aerobatic pilots, and others who desire a practical "uniform".
Members of the United States Marine Corps wore flight suits during most vehicle patrols and ground combat operations in Iraq and Afghanistan, because their standard camouflage utilities were not flame-resistant. Flight suits have now been phased out among ground personnel with the introduction of the Flame Resistant Organizational Gear, or "FROG" suit, which resembles the standard camouflage utilities.
