Indigosea M43 Cargo Pants: A Rugged, Heavy Version of the OG-107
💸
Indigosea provided these pants to me for free for purpose of independent review.
There are plenty of reasons to wear cargo pants, even if you don't need to fill every pocket. In fact, in the military we wore cargo pants as part of our daily combat uniform — and we weren't _allowed_ to put anything in the pockets (barring our berets when indoors, exclusively in the left pocket).
It's the weight and silhouette that really start speaking with a pair of pants like this, not how much capacity you can put stuff the pockets.
The extra fabric for the pocketing and reinforcements changes how the trousers hang on your body, and the pockets themselves give an otherwise simple garment some character. Having somewhere to easily put things is useful even if most days you might be carrying only your phone and keys.
When the details work well, you start finding reasons to use the pockets; even for those of us that were trained not to.
That's the biggest thing that interest me about these M43 cargo pants from Indigosea: the way they look, and the functionality they provide without ruining the way they look.
12.5OZ Cotton Reverse Sateen Cargo Pants | M43 Tactical TrousersUpgrade your outdoor or everyday gear with these durable, vintage-inspired M43 tactical pants. Engineered for both rugged functionality and timeless style, these trousers are built to last, developing a unique, personalized patina the more you wear them. Features Heavy-Duty Construction: Expertly crafted from a substanIndigoseaindigo1995
These pants combine the reverse cotton sateen material that I enjoy wearing with the mil-spec OG-107 trousers they make but use a heavier 12.5 oz material suited for the three cooler seasons.
$64.99 at the time of writing, they're within reach of someone who likes heritage clothing but doesn't want every purchase to become a major financial decision. Or, heaven forbid, using the "buy-now-pay-later" model that's becoming so prevalent today where people rack up 34%+ interest rates on a piece of clothing.

## Patterning, fabric & design
The M43 belongs to the military-inspired side of Indigosea's clothing.
This is a distinction worth making if you've read my review of their actual military-spec OG-107 fatigues. The OG-107 aim to _reproduce_ the original military fabric specification and its Type I detailing; these M43 trousers take military clothing as a _starting_ point, but ultimately have a different pocket arrangement, zipper fly and hook-and-loop hem adjustments than you'd find on a mil-spec garment.

Sharing a fabric _type_ doesn't make them the same kind of reproduction, nor even the exact same batch of material. As mentioned, the M43 is a 12.5 oz material per square yard, whereas the OG-107 is around 9 ounces. The M43 name shouldn't be taken as a promise of a regulation-correct historical garment, and this is the case with most manufacturers — naming conventions are more for descriptions and searchability than a standard.
I like accurate reproductions, but I'm not in the reenactment niche. I also very much appreciate garments that adapt the functional and stylistic ideas thoughtfully or uniquely. And these M43 pants do just that.

### Reverse cotton sateen
The fabric is the first reason I'd look at these over a generic pair of cargo pants. Back in the day I owned a lot of military-inspired garments from lesser quality stores and brands like Old Navy, Banana Republic, and J Crew. I know people might argue the latter two as being high quality, but in comparison to what Indigosea makes I would argue they're on a level below — at least with material selection specifically.
Cotton sateen has a different character from denim or canvas: its smoother surface comes from yarns that float across several crossing threads before interlacing with each other again. Cotton Incorporated's weave guide explains how those floats give satin-type weaves their smoothness and drape, along with their potential vulnerability to snagging.
With reverse sateen, the cloth is used with the smoother face on the inside, touching the legs, and the more textured reverse facing outward.
There are practical reasons for that arrangement in military clothing, like having the more comfortable side touch the body while the more rugged side makes contact and rubs against things in the outside world. The matte exterior avoids the sheen of the conventional face, which elicits patination to form.
Filson's explanation of reverse sateen describes that combination of outward durability and inward comfort and the fabric's widespread use in military fatigues.
The inside surface feels really good against my legs, and it's most noticeable when you're sliding the pants on.
The outside is equally appealing, but for a different reason: there's texture to look at from the beginning. You don't have to wait for dramatic fading to find interest in the fabric used here; as reverse sateen softens and develops with wear, its character increases.

### Heavy but not heavyweight
At 12.5 ounces, I'd put the fabric itself toward the average side of midweight. It certainly isn't lightweight, but calling it heavyweight would give the wrong impression to people accustomed to heavy denim.
Unbranded: 21oz selvedge denim made for fast, high-contrast fadesWhile the weft (underside) is red, these jeans will fade blue like any other indigo-dyed denim — these are a limited run, but what we go over in this article applies to their stock 21 ounce denim, the UB721, tooSplishedBryan
This is what I'd consider a heavyweight fabric
The trousers feel more substantial than the fabric weight suggests, though: cargo pockets, flaps, overlapping fabric and the overall construction all add up beyond being just a pair of 12.5 oz chinos or khakis. Fabric weight alone doesn't tell you how much pant you're wearing — sometimes you have to pick them up to really understand.
While I think of these as a three-season alternative to the OG-107, summer is still doable for those of us who are used to heavier materials, but I'd reach for the lighter fatigues first when keeping cool is the priority.
On something like a motorcycle in the summer, though? Absolutely perfect, especially to store your riding gear in.

## The pocketing and construction details
The cargo pockets aren't identical on both legs, which gives them a little more usefulness than a symmetrical layout might. Or maybe even just more flair or style, so to speak.
On the left leg, there's one large cargo pocket. I can get my hand into it without undoing the buttons, while the generous flap still covers the opening enough to help keep contents from falling out during ordinary use or riding.
The balance here between access and coverage is really nice. A pocket can be enormous and still be annoying if you have to fiddle with the closure every time you need to get something out of it.
The right side has two cargo pockets instead of one large compartment. That could work well for separating gear: smaller items don't all have to settle into the same space. If you're taking them to the range, those pockets could also accommodate magazines or a number of range-related gear you might be able to think of.
Look closely and you'll notice the slanted buttonholes, too: people think they're simply a visual detail, but no: they make the buttons easier to do and undo with one hand, even while gloved.
The knees have articulated pleats intended to provide room when you bend your legs. With a substantial cotton fabric, building that movement into the pattern makes sense. The pleats give the knee area shape and space to open as the leg bends, rather than relying on putting stretchy elastane in the material.
Up top, there's a YKK zipper fly, which is an everyday convenience compared with the OG-107's button fly.
There are also six belt loops. I prefer more than the usual five most pants or jeans have, so six here is very welcome; the seven on Wrangler's 13MWZ are another arrangement I like and bring up a lot.
The M43 doesn't have the OG-107's waist cinch tabs or the A-10's suspender buttons, though. Your belt handles the adjustment here, and unless the waist happens to fit you particularly well, I think pants like these usually look better with one anyway.
💡
Because of the knee articulation, buying a pair closer to your natural inseam length makes sense: when you sit, the trousers don't hike as far up your leg as non-articulated pants might. When you stand, they land right where they should instead of stacking excessively.
* * *
## Adjustable hems are actually useful
The hook-and-loop adjustment at the bottom of each leg lets you change more than just the _appearance_ of the trousers at the calf.
Left loose, the fabric can fall over any boot with room for air to flow. Tightening the hem reduces that open space, which is useful when you want to keep air out, or use it to gather the material before tucking the trousers into a boot. Bulk control and extra comfort, so to speak.
Hook & loop material (commonly referred to as a brand name "Velcro")
This helps with a particular fit detail I've noticed: when I sit down, the trouser legs rise to around the tops of my 8-inch boots. Cinching the hems could help close the small gap that would otherwise leave my legs accessible to mosquitoes, provided the fabric still overlaps the boot. Because of the articulated knee I mentioned earlier, they don't rise quite as high as 30-inch inseam typically would.
That doesn't replace having a lack of inseam length, but it does allow you to have a nicer-looking presence with the trousers while standing _or_ sitting.
Adjustable hems give you varying looks for your footwear

## Fit and sizing
Indigosea sent me Army Green color in size 32×30. That's currently the only color offered, with tagged inseam options of 30 and 32 inches (waist size options are generous).
They picked my size based on our previous collaborations — had I chosen it myself, I probably would have requested the 32-inch inseam as I do with most of my pants and jeans.
That said, I really like the way this shorter pair looks when I'm standing. The drape works well, and I wouldn't describe the length as a problem from a functional perspective. What I would have chosen very well could have looked too long on me from a fashion perspective, and with the articulated design plus adjustable hem we already talked about, the 30 inch inseam really makes sense for me here.
My natural inseam is around 30.5"; with jeans I typically buy 32 inch inseams
My tagged 30-inch pair measures 29 inches through the inseam, before I've washed it. That's worth considering if you're deciding between lengths, especially if your usual fit already leaves little room to spare.
I don't believe these will shrink much through washes (the OG-107 did not shrink in the inseam at all when I washed them), so that's likely not an issue. Bear in mind, too, that these are a high-rise and inseam length isn't the entire tell of how a pair of trousers fit.
My natural waist is about 31 inches, while these measure 16.5 inches across the waistband, or roughly 33 inches around. I don't mind that additional room, particularly with a higher rise. It leaves space for my stomach to expand when sitting, or after eating, and it can accommodate a weapon holster without making things feel tight.
Indigosea describes the cut as a relaxed mid-rise, but the 12.5-inch front rise on my pair is pretty telling of my own standard: it's a high rise. I'd pay more attention to the measurement and where it sits on your body than how something is labeled, of course.
💡
For another perspective, one buyer on Indigosea's Loox review page described the M43 as comfortable but slightly too long for him. His selected size wasn't shown in the review I found, so that doesn't establish a sizing rule. It does reinforce why __your own__ proportions and preferred length matter more than someone else's overall verdict on fit.

## Measurements
These are the measurements of my own pair in size 32×30, unwashed. The hem measurement is with the adjustment open.
Measurement | Inches
---|---
Waist | 16.5"
Thigh | 13.6"
Seat | 21.9"
Knee | 9.9"
Inseam | 29"
Front rise | 12.5"
Back rise | 17"
Hem opening | 9"
Full length | 40.5"
I haven't washed these yet, so I can't give an honest before-and-after comparison or say how much they'll shrink. What I can say is that my OG-107 pants shrank 0% in the inseam when I washed those.
💡
A cold wash followed by line-drying outside of direct sunlight is my usual approach when I want to limit shrinkage and preserve a similar fit of a garment. I'll update this section and chart with shrink percentages in the future if they vary enough to do so.

## Indigosea M43 vs. OG-107 comparisons
The easiest way for me to place the M43 is as a heavier companion to the OG-107 because they're the only two trousers I currently own that use a reverse cotton sateen.
The OG-107 is the simpler, lighter fatigue trouser with _reproduction_ details. The M43 adds cargo storage, articulated knees and adjustable hems, and its Army Green is an entirely different shade from the OG-107's green.
Detail | Indigosea M43 | Indigosea OG-107
---|---|---
Approach | Military-inspired cargo trousers | Type I repro with military-spec fabric
Fabric | 12.5 oz reverse cotton sateen | 9 oz reverse cotton sateen
Leg pockets | One large left cargo pocket; two on the right | No thigh cargo pockets
Fly | YKK zipper | Buttons
Waist adjustment | Belt; 6 loops | Belt; 5 loops + side adjustment tabs
Hem adjustment | Hook-and-loop tabs | No equivalent hem tabs
I'd choose the OG-107 when I want a straightforward fatigue pant or something easier to wear in the heat. The M43 makes more sense when I want extra storage and a more substantial trouser while keeping that comfortable sateen against my skin.

## Wrapping up: worthwhile cargo pants?
So far, the M43 makes a really convincing case for itself at only $65 —
It's a military inspired garment made to a standard that heritage/Americana fans expect. There are no cheap materials used or corners cut when it comes to anything I've handled from Indigosea, let alone these cargo pants.
The fabric feels good, the pockets offer different ways to carry a lot of things, and the hem adjustments give me control over how the pants sit around various styles of boots.
These are an appealing option if you like the OG-107's fabric but want something with more heft and utility. A good pair of cargo pants should make you want to wear them even when you don't need all the pockets, and these do that for me.
