Nomex flying suit trousers : 1st Air Cavalry Division, United States Army

Nomex flying suit trousers with concealed zip fly. The trousers feature a waistband with seven belt loops and a black metal buckle on each side with a fabric tab for tightening. There are two diagonal inset front pockets with concealed button flaps and two rear patch pockets with concealed button flaps.
