The Fishtail Parka - How an Army Coat Became a Mod Uniform

What the fishtail parka actually is

Ask someone to picture a mod and you will probably get two images at once: a sharp, narrow suit, and a bulky olive green coat worn over the top of it. That coat is the fishtail parka, named for the long, split tail at the back that could be tied around each leg to seal in warmth. It looks nothing like the suit underneath, and that contrast is the whole point. The parka was never meant to be fashion. It was meant to be armor for your good clothes.

You will still see it today, on scooter riders, on revival mods, and on anyone who has absorbed the look secondhand through music and film without knowing where it started. Understanding that starting point changes how you read the coat. It was not designed by a tailor chasing a trend. It was designed by the military for men trying to survive in brutal cold, and its second life as a style statement came almost by accident.

Historical origins: from Korea to Carnaby Street

In the years after the Second World War, US military planners kept refining cold weather gear, and that work led to the parka that became known as the M-51, officially adopted in 1951 for the brutal cold of the Korean War. It came too late to reach most troops in large numbers before the fighting ended in 1953, so many soldiers on the ground were still wearing older WWII-era cold weather gear, but the M-51 became the template that stuck. These coats needed to do a specific job: keep a soldier warm and mobile in extreme cold without the stiffness of a heavy overcoat. The solution was a long, loose shell with a fur trimmed hood, a quilted liner that could be zipped out, and that distinctive fishtail hem at the back, designed to be gathered and tied for extra insulation around the legs. Later revisions refined the pattern further, but the basic shape held: functional, oversized, built for weather rather than looks.

None of that had anything to do with British youth culture yet. That connection happened later, and almost sideways. By the late 1950s and into the early 1960s, army surplus stores in Britain were full of these coats, sold cheap because the military had moved on to newer equipment. Around the same time, a new youth subculture was forming around sharp tailoring, modern jazz and soul records, and Italian scooters. The mods took enormous pride in their suits, and riding a Vespa or Lambretta through London traffic in the rain was a direct threat to that investment. The parka solved the problem: it was cheap, it was roomy enough to go over a suit, it was reasonably weatherproof, and the hood could be cinched tight around the face in an era before scooter helmets were standard. Practically nobody else on the street was wearing one, which mattered just as much as the practicality did.

By the early 1960s the parka had gone from a practical workaround to part of the uniform itself, worn as much for its look as for what it protected. When The Who built their 1973 concept album Quadrophenia around a young mod caught between identity and belonging, and when the film adaptation followed in 1979, the parka appeared throughout as visual shorthand for the whole scene: scooters, suits, and packs of parka clad mods heading to seaside towns like Brighton. That film did more than any single event to fix the coat in the public imagination as mod clothing rather than army surplus.

Key elements of the design

A genuine fishtail parka has a handful of features that separate it from any generic winter coat. The extended, forked tail at the back is the obvious one, long enough to be tied around the thighs for warmth on a moving scooter. The hood is typically trimmed in fur or a fur style ruff, deep enough to shield the face from wind. The shell is a tough, water resistant cotton or nylon blend, roomy enough to fit comfortably over a suit jacket without restricting movement. Inside, a quilted liner, often removable, provided the actual warmth, which meant the same coat could be adjusted for the season. Pockets, a drawstring waist, and heavy duty snap or zip closures round out the practical details. None of it was designed with fashion in mind, which is exactly why it reads as authentic decades later: every feature has a functional reason to exist.

Modern context and evolution

The parka never really left. The late 1970s mod revival, driven in large part by Quadrophenia, brought it back onto British high streets and school yards in force. In the 1990s, Britpop gave it another life: Liam Gallagher of Oasis wore the parka as a near constant part of his stage and street image, drawing directly on the Quadrophenia era mod look and passing it on to a new generation who had never heard of the original scooter clubs. Each revival added a layer of meaning to the coat without erasing the one before it. Today you can buy fishtail parkas from military surplus shops, from heritage outdoor brands, and from fashion labels that have reinterpreted the cut for a slimmer, less utilitarian silhouette. Some buyers want the mod association specifically. Many just want a genuinely warm, well built winter coat and are only vaguely aware of the history stitched into it.

Common misconceptions

The most common mistake is treating the parka as something mods invented. They did not design it, name it, or manufacture it. They repurposed military surplus that was cheap and available, and turned a practical choice into a style signature through repetition and shared identity. It is also worth separating the coat from any single subculture’s politics or attitude. The mod scene itself was broad, spanning different tastes in music and different levels of scooter and suit obsession, and the parka was common ground across most of it rather than a marker of one faction. Finally, people sometimes assume the fur trimmed hood is a modern fashion addition. It was there from the start, a functional response to genuinely harsh weather, long before anyone was wearing the coat to look a certain way.

FAQ

Is the fishtail parka the same as the M-65 field jacket? No, and this one trips people up because of the naming. The M-65 most people mean is the short, waist length combat field jacket. But there is also a later fishtail parka that carries the same M-65 designation, produced from 1968 as the last major revision of the M-51 fishtail line. Two different garments ended up sharing a model number from the same mid-1960s design generation, which is where the confusion comes from. Either way, the fishtail parka proper is the long, hooded coat with the split tail hem, not the short field jacket.

Why is it called a fishtail parka? Because of the long, forked hem at the back, split down the middle in a shape that resembles a fish’s tail. That hem could be tied around each leg for extra warmth, which was the original functional reason for the shape.

Do you have to be into mod culture to wear one? No. Plenty of people wear fishtail parkas purely as a warm, durable winter coat with no scene affiliation at all. The subculture association is real, but it is not a requirement.
