These U.S. Army 4th Model Jungle Fatigue Pants are iconic pieces from the Vietnam War era. The size is X-LARGE-REGULAR, which is the largest available.

The label reads “TROUSERS, MAN’S, COTTON WR POPLIN, ‘RIP-STOP’, OG 107,” and the pants are made of 100% cotton ripstop fabric.The contract number is “CONT. NO. 7071,” indicating that this pair likely dates from around 1968.

The 4th Model can be considered the definitive version of the jungle fatigue pants, embodying functional beauty designed for combat in tropical regions—featuring lightweight ripstop fabric, large cargo pockets, waist adjusters on both sides, and a drawcord at the hem. It is a highly refined piece, even when viewed as the origin of modern cargo pants.

And perhaps its greatest appeal is the “X-LARGE REGULAR” size—the largest available. The label specifies a waist of 39–43 inches and an inseam of 29 1/2–32 1/2 inches.With vintage jungle fatigues, larger sizes are overwhelmingly harder to find, so this pair is especially recommended for those who have been searching for a pair that actually fits loosely.

This is a pre-washed, used pair; while it shows some fading and signs of wear, it’s in good condition considering its age. The texture of the ripstop fabric and the well-worn OG-107 color create a truly distinctive look. Combining the perfect trio of size, era, and practicality, this is an authentic Vietnam War-era piece you can wear and enjoy to the fullest.
