What Are Cargo Pants?
Definition
Cargo pants are casual trousers with large cargo pockets, usually flapped and pleated, on the sides of the legs at thigh level. They differ from chinos and jeans mainly in those outside leg pockets, a feature taken from military field dress such as British battledress, whose trousers carried a map pocket on the thigh.

Where do cargo pants come from?
Cargo pants come from military field dress, where pockets on the leg let soldiers carry kit. Their move into popular culture is dated to the 1970s, when army surplus became civilian dress. The name is younger than the design. Merriam-Webster dates the first known use of “cargo pants” to 1951, and of “cargo pocket” to 1974.
British battledress
Military Times, citing the author Brian Jewell, traces the earliest cargo pant to the pocketed trousers British soldiers wore with battledress in the 1930s. The same article says the battledress design was complete by 1937 and clothed servicemen for more than 25 years.
A later privately tailored officer’s pair of khaki serge battledress trousers at Imperial War Museums, which the museum associates with the period 1945–1989, shows the layout. It has a map pocket on the front of the upper left leg and a small pleated shell dressing pocket on the upper right. Its pocket buttons are concealed.
Paratroopers in the Second World War
Military Times reports that the United States, notably its paratroopers, modelled its Second World War uniforms closely on battledress. The National Museum of the US Air Force notes that American paratroopers wore specialised jump suits with large pockets for extra rations, ammunition or grenades.
From surplus to fashion
A 2013 peer-reviewed study by Joseph Hancock and Edward Augustyn places the start of the move into popular culture in the 1970s, when hippies wore army surplus to protest against the Vietnam War. That ties the garment to hippie fashion. The authors name the military, subcultural style, film, media, retail and merchandising as the routes into mass fashion. Military Times calls the 1990s the civilian heyday of cargo pants.
Hancock and Augustyn also set out to examine “the origins, histories and myths” around cargo pants as a military garment. Treat any neat claim about a single first pair with caution.
What makes cargo pants cargo pants?
Cargo pants are defined by large cargo pockets on the legs, typically on the sides at thigh level. Remove those pockets and you have ordinary casual trousers.
Merriam-Webster defines a cargo pocket as a large pocket, usually with a flap and a pleat. The flap closes over the opening. The pleat folds out so the pocket can take something bulky, which a flat patch pocket cannot do as well.
The rest of the garment is usually conventional. The Imperial War Museums battledress pair, for example, also has a fly front, slanted hip pockets and a flapped rear pocket. Civilian pairs follow the same pattern, with a button or zip fly and standard front and back pockets.
Cargo pants vs look-alikes
| Garment | Leg pockets? | How to tell it apart |
|---|---|---|
| Cargo pants | Yes, at the thigh | Large flapped, pleated pocket on the outside of the leg |
| Chinos | No | Cotton twill trousers, typically with slanted side pockets |
| Jeans | No | Denim, usually with front and back pockets only |
| Cargo joggers | Yes | Cargo pockets on a softer, often knitted trouser with elasticated cuffs, closer to sweatpants |
What are the main types of cargo pants?
Cargo pants mainly vary by leg shape, cloth and how close they stay to military issue. The pocket is the constant; everything around it changes.
| Type | How to recognise it |
|---|---|
| Military issue and surplus | Drab colours or camouflage print, pocket layouts set by a specific uniform pattern |
| Relaxed or wide-leg | A straight or wide-leg cut with room through the thigh, so full pockets hang freely |
| Tapered | Narrows to the ankle, like a tapered leg, often with a cuff or drawcord at the hem |
| Cargo joggers | Soft cloth, elasticated waist and cuffs |
| Cargo shorts | The same pocket on a leg cut above the knee |
How do you tell well-made cargo pants?
Well-made cargo pants have working pockets that expand, corners reinforced against the pull of a load, and double stitching where the seams take strain. These checks take a minute in a fitting room.
Check that the pocket works
- Find the pleat. Lift the flap and pull the pocket away from the leg. A true cargo pocket has a pleat that opens out, as in Merriam-Webster’s definition. A flat pocket with a flap stitched above it holds far less.
- Close the flap. It should cover the opening fully when fastened. A flap narrower than the opening lets things slip out when you sit or crouch.
- Load it. Put a phone and keys in each thigh pocket, then sit and squat. The pocket should sit on the side or front of the thigh, where you can reach it, without dragging the waistband down.
Look at the stitching
New Mexico State University’s extension guide to judging clothing gives the benchmarks. It looks for shortened stitches to reinforce corners, straight and even seam stitching, and double stitching in the crotch seam. It also checks for a waistline that is taped or double stitched, and a zip that is properly finished and lies smooth.
- Pocket corners: Look at the top corners of each cargo pocket, where a full pocket pulls hardest. You want a run of shortened, denser stitches there, not a single loose pass.
- Crotch seam: Turn the trousers inside out. Two rows of stitching along the crotch seam are a good sign.
- Waistband: Look for tape or a second row of stitching inside the waist.
- Zip: It should lie flat under its placket. Run it up and down a few times to check it does not catch.
Red flags
- No pleat, so the cargo pocket is decoration rather than storage
- Single-pass stitching at pocket corners
- Wavy or uneven topstitching around the pocket edges
- A single row of stitching in the crotch seam
How do you wear cargo pants?
Wear cargo pants as casual trousers, and balance their bulk at the thigh with a simpler, closer top half. The leg pockets add width, so the rest of the outfit should not add more.
- Keep the pockets light. Full pockets push the leg outwards. For everyday wear, carry small, flat things in them.
- Balance the proportions. With a wide pair, wear a fitted knit or a tucked-in shirt. With a tapered pair, a looser top or overshirt works.
- Mind the hem. Wide cargo pants look best breaking over a sturdy shoe. Cuffed or tapered pairs suit trainers or boots that show the ankle.
- Use one military reference at a time. Olive cargo pants with a plain top read as streetwear. Adding camouflage, a field jacket and boots pushes the look into full military-inspired fashion.
- Dress them up with cloth, not tailoring. A neat cotton twill pair in navy, black or stone, with a knit polo or crisp shirt, is about as smart as cargo pants get.
Frequently asked questions
Why are they called cargo pants?
The name describes their cargo pockets, the large leg pockets made to carry a load. Merriam-Webster records “cargo pants” from 1951, before “cargo pocket” (1974). It defines a cargo pocket as a large pocket, usually with a flap and a pleat, and cargo pants as trousers with those pockets, typically on the sides of the legs at thigh level.
What is the side pocket on cargo pants for?
It was made to carry kit. On a British battledress pair at Imperial War Museums, the left thigh pocket is a map pocket and a smaller pleated pocket on the right leg held a shell dressing. The National Museum of the US Air Force notes that Second World War paratroopers used large pockets for extra rations, ammunition or grenades.
Are cargo pants military clothing?
They began as military clothing and are now mostly civilian. Military Times, citing the author Brian Jewell, traces them to the pocketed battledress trousers British soldiers wore in the 1930s. A 2013 peer-reviewed study by Hancock and Augustyn describes how cargo pants went from a military uniform to a popular casual trouser. The National Museum of the US Air Force notes that Second World War paratroopers also relied on large pockets.
When were cargo pants popular?
Military Times describes the 1990s as the heyday of cargo pants among civilians. Hancock and Augustyn’s 2013 study credits the military, subcultural style, film, media, retail and merchandising with carrying them into mass fashion. The same Military Times article traces their earliest form to British battledress trousers of the 1930s.
Can you wear cargo pants to work?
Only where casual dress is accepted. Cargo pants are a casual trouser, and the thigh pockets keep them informal however they are styled. For a neater result, choose a plain pair in a dark or neutral cotton twill with pockets that lie close to the leg. Wear them with a crisp shirt or fine knit, and keep the pockets empty so the line stays clean.
