The year is 1972. At the base of Half Dome in Yosemite Valley, hikers, climbers, and families are all adjusting their packs, tightening their boots, and preparing for a long day in the mountains. The outdoor recreation boom was sweeping across America, and everyone had one thing in common: a love for the mountains. And a brightly colored, hooded mountain parka.
Every decade has its defining piece of outerwear. The 1920s had tailored trench coats, the 1950s had leather jackets, and in 1970s America, it was the mountain parka. Durable, practical, and outrageously bold, it borrowed from military design but was entirely reimagined for a generation trading parade grounds for granite walls and alpine trails.
Almost everyone with a sewing machine tried to produce one. Some were decent; many were not. But one brand quickly rose above the rest: Sierra Designs. Their Mountain Parka became the jacket everyone wanted, visible from miles away in deep blues, forest greens, and vibrant oranges.
While other brands experimented with cheaper fabrics or early waterproof technologies, Sierra Designs stayed loyal to a simple 60/40 cotton-nylon blend. The genius of this fabric was in its simplicity. It was tough enough to withstand falling rocks, gorse bushes, and the occasional cigarette burn. When the fabric got wet, the cotton fibres swelled, tightening the weave and naturally keeping moisture out. It wasn’t flashy. It wasn’t experimental. But it was dependable.
The Mountain Parka quickly became more than a utilitarian garment. It became a cultural symbol, a visual shorthand for the 1970s outdoor adventurer. Its pockets could hold binoculars, compasses, snacks, and anything else a hiker might need, while its long cut offered extra warmth against wind and snow.
Another element that would catapult the Mountain Parka into the history books was its film cameos – most notably Michael Cimino’s 1978 masterpiece, The Deer Hunter. The movie’s snowy Pennsylvania scenes and long, rugged treks through the wilderness immortalised the mountain parka in cinematic history. Decades later, one of cinema’s enduring debates is whether Robert De Niro’s bright orange parka was actually a Sierra Designs jacket. Collectors, fans, and jacket aficionados across the world have argued endlessly – some swear it was, others are just as adamant it wasn’t – but the discussion has only added to the garment’s mythic status.
Over time, the Sierra Designs Mountain Parka has evolved in small ways, but its essential design has remained constant. Zip closures, adjustable hoods, and reinforced stitching. It has undoubtedly earned itself a pole position in the outdoor history books, celebrated by generations of hikers, climbers, and urban adventurers alike.
And the beautiful thing is that a well-cared-for Sierra Designs Mountain Parka made in the early 1970s will still be perfectly wearable today. Allowing the garments to be passed down through generations – from one adventurer to the next.
But if you’d rather have one fresh from the source, Sierra Designs still makes them exactly as they were back then. Same bold colours, same fit, same attention to detail. The 60/40 cotton-nylon blend, the generous pockets, the long cut – all exactly as the brand originally intended. It’s rare to find an outdoor garment that manages to feel both historic and fully relevant at the same time, but Sierra Design’s Mountain Parka does just that.
Its long-lasting appeal isn’t simply about durability or cultural relevance – there’s genuine character in the design. Each seam is begging out for adventure – where other pieces of outdoor history want framing and hanging on a wall – Sierra Design’s Mountain Parka wants the total opposite.
That combination of practicality, boldness, and storytelling has kept the Mountain Parka in circulation for over fifty years. From its origins in the 1970s outdoor boom to the mountains and forests of today, it remains as capable as ever. Whether worn by a weekend hiker, a devoted climber, or someone simply after a jacket they can wear to death.
We recently headed to the mountains to put the Sierra Designs Mountain Parka to the test for an upcoming issue of Proper Magazine – gaining a firsthand insight as to why a jacket that first captured the imagination of adventurers and cinephiles alike continues to be considered one of the greatest pieces of outerwear ever made.
