Engineered for serious adventurers, this puffer down jacket combines Japanese-designed construction with premium materials for uncompromising performance. The 1000 fill power down delivers exceptional warmth-to-weight ratio, while the Pertex Quantum outer fabric provides a featherlight shell that resists wind and moisture without bulk. The result is a jacket that insulates efficiently in cold conditions whilst remaining packable enough for any expedition. Black colourway suits versatile layering across varied terrain and seasons.
