The Ultimate Guide To The M65 Field Jacket

While the other military silhouettes have evolved a great deal from their battle-ready originals, the M65 has steadfastly maintained its war-time credentials as a rugged and versatile lightweight jacket.

Out of the grim realities of war have come numerous menswear garments that have transcended their utility in battle to become integral parts of the male psyche as well as his wardrobe. From the bomber jacket to the trench coat via the pea coat and parka, military silhouettes still provide the backbone of contemporary men’s style.

And while the aforementioned classics are sophisticated and masculine in their own unique ways, one piece of outerwear that often flies under the radar is the M65 field jacket, as worn by Al Pacino in Taxi Driver (1976), Dustin Hoffman in Kramer vs. Kramer (1979) and Daniel Kaluuya in Judas and the Black Messiah (2021). While the other military silhouettes have evolved a great deal from the battle-ready originals, the M65 has steadfastly maintained its war-time credentials as a rugged and versatile lightweight jacket.

History of the M65 field jacket

As always with military garments, the ones still with us on Civilian Street today are the product of a long line of evolutions and upgrades. The ’65’ part of the M jacket refers to the date it was launched, but it wasn’t the first of the ‘M’ jackets. That accolade goes to the M41, which was a light- to medium-weight waterproof cotton field jacket featuring four front bellows pockets to carry ammunition, first aid kits and whatever else soldiers deemed important enough to store on their person.

Field jackets had existed long before the khaki green M41 in the form of hunting attire, but the onset of World War II led the US Army to outfit their GIs in the M41, which itself referenced civilian windbreakers. Previous to that, troops would have been issued heavy wool four-pocket jackets – which might have been fine for the trenches of World War I, but were not suitable for the more agile and dynamic mid-century soldier.

Two years later the M43 was introduced, cut in a cotton sateen cloth to the same four-pocket configuration. This later evolved to become the M51, and the now-iconic M65. Which in turn evolved into the equally iconic M-1951 and M-1965 variations that remain popular for civilian dress today.

The M65 is a hip-length jacket – anything shorter veers into blouson/bomber territory. Vintage versions will often have epaulets and sometimes an internal drawstring or external belt to create a waisted silhouette (the military purpose of this was to retain heat and prevent the jacket getting caught in dense undergrowth), but most modern designs have done away with any overly military affectations in favour of a more minimalist aesthetic.

The original M65 came exclusively in lightweight yet hardwearing materials such as cotton drill, sateen or a nylon-cotton mix.

Today’s styles are still likely to be cut from cotton cloths (or linen in summer-weight field jackets) but you can also find high-end luxury styles in buttery-soft suede.

While the early M41 versions came with a front button fastening, the M65 benefitted from a zip-fastening upgrade. And that’s still true for most contemporary M65 iterations. The button fastenings on the four bellows pockets also shifted away from buttons, adopting snap fastenings instead.

An exterior belt is not strictly speaking an original detail from the M65 but has become a more modern feature off the back of the popularity of belted safari jackets. Given its propensity for creating a more flattering silhouette at the waist, that’s no bad thing.

How to wear an M65 field jacket

Styling the M65 jacket largely depends on what it has been constructed from, since luxurious fabrics such as suede will naturally complement more sartorial looks. If you like the vibe of the original – i.e. a midweight cotton twill in the classic olive drab or khaki tones – then there are myriad ways you can wear it.

A grungy option is to combine it with jeans and a tee to reference the iconic Travis Bickle look from Scorsese’s Taxi Driver (1976). However, the same vintage style also makes a nice juxtaposition to a tailored pair of pleated trousers and loafers.

Mixing a military/workwear classic with a smart aesthetic is something we’ve seen a lot of recently, especially at Pitti Uomo, the menswear expo in Florence. Italian showroom owner and fashion influencer Alessandro Squarzi (@alessandrosquarzi) is an excellent proponent of the M65, which he often styles with a simple white tee, selvedge denim or cotton chinos and loafers.

If your aesthetic is more fashion forward, the M65 is still really effective as a vintage layer over contemporary streetwear, adding some thought and authenticity to an already label-rich look.
