It keeps you safe without weighing you down. This Flight Suit is built to military specification FNS/PD 96-17 (MIL-C-83141A) as worn by all U.S. flight crews. Made with flame-resistant, non-melting fabric, our suit features a two-way zipper with reinforced pull. Six primary pockets make for ample carrying space, while an adjustable waist belt with hook and loop closure makes these suits easily adjustable and fitting all body types. The felled seams and a bi-swing back add to the lightweight and comfortable design. Colors are NIR compliant.
