The M-65 field coat: one of the most iconic jackets you need to buy
The jacket is a practical icon that still holds up in modern times
The M-65 field jacket sits in a rare category of military gear that never really left public circulation once it started being issued to U.S. soldiers.
It may have started as a functional upgrade for troops in the field, but decades later it's just as relevant in civilian wardrobes — whether from vintage markets or modern repro shops.
When I joined the military, it happened to be the year that the M-65 was fully phased out, in 2009. So while I never got one of these jackets myself, my dad and brother both served during times when the M-65 field coat was still issued to military personnel.
The M-65 jacket that I bought, and what to look for when buying one yourself
Vintage 1960s-1970s commercial M-65 field coat
💡
Coat, Cold Weather, Man’s, Field ; Stock Number: 8405-634-5333; WPL 10881 (Corinth Manufacturing Co.)
The jacket I bought off of eBay is a Vietnam-era jacket (civilian production) made around the late 1960s to early 1970s.
A cool thing about M-65s is that we can discern who made the jacket, and when, based on a large tag placed on the inside of each one.

|---|---|---|---|---|
| Epaulettes | None (Rarest) | Added to shoulders | Standard | Standard |
| Zippers | Aluminum | Aluminum | Brass | Nylon |
| Cuffs | Gusseted (fold-out flaps) | Phased out by 1968 | Straight/Simple | Straight/Simple |
| Colors | Olive Green (OG-107) | Olive Green (OG-107) | Woodland Camo (added 1980) | Desert/UCP (post-1990) |
Material of the label
Commercially sold jackets often feature white, paper-like labels rather than the off-white or tan cheesecloth-like cotton labels found in official military contracts.

My jacket's label
The manufacturer associated with WPL 10881 is the Corinth Manufacturing Company, based out of Corinth, Mississippi.
WPL or RN vs. military issue
The WPL or RN is the easiest way of knowing whether the vintage M-65 you're looking at is an actual government-issued garment, or from a commercial production run. While they use the same military specs and standards either way, the labeling is differen t.
WPL stands for Wool Products Labeling , which is an older FTC (Federal Trade Commission) standard that has been replaced by the RN (Registered Identification Number) system. A good example of finding info from the RN is my Indiana Jones jacket and Indiana Jones fur felt hat, both of which don't have brand markings on the inside.
Contract numbers
Lines like #AC 601-287-2279 on these label looks official, but they're internal or fabricated stock numbers and don't correspond to DoD (Department of Defense) procurement records.
In a government-issued M-65 jacket, you'd see something more along the lines of DLA100-79-C-2904 .
Authenticity tip
For enthusiasts looking for "true vintage," these Corinth jackets are considered excellent and period-correct civilian wear, which are made to the same specifications as the military version, thus also accept the cold weather liner.
Buzz Rickson's Type M-65 LINER. Also at Blue in Green, Franklin & Poe
🧵
The materials the liner consists of are 100% nylon shell + 100% polyester fill. Most M-65 jackets won't come with the liner, but brands like Cockpit USA include new old stock liners with their M-65 jackets.
Commercial M-65 field jackets were frequently sold in army-navy surplus stores during the post-Vietnam era to people who wanted the military look and utility without the conditions that come from buying used.
Why the "WPL" remains relevant today
A WPL number instead of an RN number is a hallmark of legacy American manufacturing. Because Corinth Manufacturing Co. (and other companies at the time) was assigned its ID number before the year 1959, finding garments with this makes for easier identification of a vintage or potentially valuable item.
Silver vs. brass zippers
In both military and high-end civilian production from the 60s-70s era, the material of the zipper was a primary change in the design:
- Silver (aluminum): used on the "2nd pattern" M-65 from roughly 1966 to 1971. These are often the most sought-after because they cover the peak years of The Vietnam War.
- Brass: standardized in 1972 and used until approximately 1985. While brass can be plated to look silver, it was not common for these specific utility jackets; if it looks silver, it's almost certainly aluminum if the zipper wasn't replaced.
Brass zippers will typically be more durable and longer-lasting than aluminum, at the cost of being heavier.

A quick history of the M-65 jacket
The M-65 replaced the earlier M-51 field jacket (which replaced the M-43) in the year 1965, and the jacket was designed to improve adaptability in varied climates.
Evolution from left to right: the M-1941 field coat, the M-1951 field coat, and the M-1965 field coat
While there are different models of the M-jackets, there are also different variants of the M-65 due to military contracts evolving over time.
Key changes to the M-65 over its earlier variants:
- A nylon/cotton sateen blend became more prevalent over 100% cotton sateen. This produces a lighter weight, more durable jacket and you'll usually hear the term NyCo in the context of this material.
- Brass zipper replaces aluminum for more durability, then eventually to nylon zippers for cost effectiveness.
- Velcro cuff hand protector eventually gets removed due to perceived redundancy of the feature with the presence of modern gear.
- Compatibility with a button-in liner stays the same for the entire history of the M-65 jacket, civilian or military issued (as long as they are contracted, reproductions, or civilian models, and not knockoffs)
Production for the jackets that most people prefer ran from 1965 through the 1980s — before the transition into variants like the woodland camo pattern and the universal camo pattern (UCP), which had the synthetic zippers added.
What is OG-107?
"OG-107" refers to the olive green shade #107 , the standard solid green used before camouflage patterns became dominant within the U.S. military.
Collectors and buyers typically prefer:
- Earlier OG-107 jackets (mid-60s to early 70s) and trousers
- They have heavier 100% cotton fabric and are considered to have better aging characteristics
- More correct appearance for period roleplays & LARPs versus the later variants
Zippers are one of the biggest indicators of value and era for an M-65 jacket
Zippers are one of the easiest ways to date and evaluate an M-65 field coat and which variant it might be.
What to look for:
- Early models (Vietnam era) :
- Aluminum or brass zippers
- Zipper brands like Scovill , Conmar , General
- Later models (70s–80s) :
- Brass, but construction can vary
- Modern jackets, end of life (80s–2009) :
- Plastic zippers, VISLON (YKK) brand
Why it matters:
- Original metal zippers age well and rarely fail
- Replacement zippers hurt collector value significantly
How the M-65 jacket and military clothing is made
The U.S. military outsources the manufacturing of its garments to US-based companies that are able to do so for the lowest cost. Usually contractors win government bids; this was a particularly strong way for companies to bolster their longevity and worldwide footprint since world war I.
Some of the more recognized names of military contractors that made the M-65 field coat include:
- Alpha Industries
- Corinth Manufacturing Co.
- John Ownbey Co.
- So-Sew Styles
- Winfield Manufacturing
- Gibraltar Industries
These names don't change function, but they do matter for authenticity and sometimes desirability.
The liner system (often not included)
The M-65 was designed as a shell system , not as a standalone winter coat. Because of this, its versatility extends to cold months by adding to it — while its default state is suitable for warmer weather.
- Issued setup includes a button-in quilted liner marked the same size as the jacket (e.g. a size medium liner fits in a size medium M-65 field coat)
- Liners are often missing on the secondhand market since many people keep them out, choosing to layer instead of button a liner into their jacket
Having the correct liner can:
* Increase seasonal usability
* Increase value

Cockpit USA includes a liner with their M-65 jackets, but only for sizes medium and larger, and the buttons won't match (but the liner will fit).
Fit and wearability
M-65 jackets are:
- Boxy and run large by design, with adjustment points
- intended for layering, and to fit ballistic plate armor underneath
With just the shell and its lightweight cotton lining, the jacket is modular enough to be used throughout 4 seasons when accounting for your other clothes and the optional poly-filled nylon liner to fill in gaps in temperature.
The zip-in hood
The hood is rarely used by civilians and service members, but it can take light drizzle before it starts to soak through.
Many unfaithful reproductions of the M-65 field coat don't contain a hood inside the zippered collar, if the zipper is even functional at all.
Why the M-65 still matters today
The M-65 is one of the few direct military garments that successfully transitioned into several different categories:
- Streetwear
- Workwear
- Heritage inspired fashion
We can easily make the argument that militaries around the world set the standard on good-looking, functional and sturdy garments, but the items are not usually directly worn — rather, brands and pattern-makers draw inspiration from military garments and those items become popular; in this case the garment is already made, popular, and people don't typically seek re-creations of the M-65.
It's been worn across decades by:
- Military personnel
- Film and pop culture figures
- Designers and brands reinterpreting it endlessly
And yet, the original still holds up. Not because of nostalgia, but because the design was already solved from the start.
Why field jackets are the most versatile style, and how you can buy a GOOD oneField jackets have virtually always been a popular style of jacket, ever since their introduction during World War II as the M-41 field jacket.

Final assessment of the M-65
The M-65 field coat isn't just a stylistic piece for fashionistas — it's a functional artifact that still does exactly what it was designed to do, and makes you look good while you're doing it.
Whether you find a vintage one in good condition or buy new, you'll quickly learn that the M-1965 is one of the best jackets you could ever own.
