My jump trousers. Same deal. You'll notice a fob pocket for a pocket watch, the designed cargo pockets and the buttons for suspenders. Also rigger modified.
The cargo pockets were rigger modified by reinforcing the pocket bellows, and by adding extra material on the inside of the leg so you can tie the top of your bulging pockets shut so they won't come open during a jump. Sadly my pockets aren't bulging to show you how well they work...
Reinforced Pocket:
Reinforced Knees:
The trouser legs taper to facilitate blousing them into your boots.
