Established in 2021, London-based Purple Mountain Observatory operates where urban landscape meets alpine performance. Two worlds that were never meant to coexist, brought together through technical outerwear that refuses to compromise. The mandate is simple: build garments that stand up to the elements, then push design somewhere it hasn’t been before. Proven technology meets experimental thinking, with little interest in following the rules of conventional outerwear.
Founded by outdoor enthusiasts Matt Braun and Georgia Smith, PMO set out to make pieces that pair technical materials with modern design. They approach every garment with the same principle: nothing leaves the drawing board without earning its place. Materials are selected with intent, construction is put to the test, and every piece is pushed through rigorous real-world conditions alongside the brand’s community.
“Every detail, from articulated patterning to lightweight hardware, is calibrated for
being on the move.”
- Matt Braun, Founder.
Purple Mountain Observatory Waves Puffer Jacket / Apple
The Purple Mountain Observatory Waves Puffa Jacket is built as a lightweight insulation layer that delivers serious warmth without unnecessary bulk. RDS-certified 800-fill-power duck down is distributed through engineered wave baffles to retain heat across key areas, while the high-shine ripstop shell keeps the technical profile distinctive. Adjustable hood and hem systems, a high protective placket and fleece-lined pockets finish a packable layer designed for cold-weather movement, travel and changing conditions.

Gender-neutral by design, the collection is built around adaptable layering, movement, and versatility across body types and environments. The result is a range that isn’t just wearable for everyone, but wearable everywhere.
Their latest collection discovers a new realm of colour, by introducing the Apple 800FP Down Puffer, and the earth-toned Heat-Reactive Obsidian Shell along with the remaining selection of garments and accessories. The Down Puffer provides compact, lightweight warmth for technical layering, multi-day expeditions, and day-to-day functionality; whereas, the Obsidian Shell marks an ongoing PMO narrative, experimenting with a thermochromic outer layer that creates a dynamic visual experience when paired with evolving temperatures.
It’s an exciting time for experimental outerwear, and Purple Mountain Observatory is at the forefront of the movement.
