The Purple Mountain Observatory Obsidian Breeze Jacket in Black combines technical fabric innovation with everyday functionality, making it a standout piece for active wearers. The jacket’s heat-reactive fabric changes appearance with rising temperatures, creating a dynamic look that adapts to your environment. Once cooled, the colour shifts back, delivering a unique thermochromic effect that reflects the brand’s focus on progressive design.

Performance is at the core of the Obsidian range. The action back construction and breathable mesh lining promote freedom of movement and ventilation, ensuring all-day comfort during high-output activity. A ventilated back yoke further enhances airflow, helping regulate body temperature in changing conditions. Practical features include welted side-entry pockets for essentials, a double-ended YKK® Vislon™ zip for versatile wear, and a toggled hem and hood that adjust for a secure fit. Built for both adaptability and comfort, the Obsidian Breeze Jacket offers technical innovation with reliable everyday wearability.
