Purple Mountain Observatory Heatreactive Obsidian Shell Jacket

Built with a heat-reactive nylon shell, this jacket shifts with temperature changes, bringing a subtle thermochromic effect that reacts as you move through different conditions. Fully taped seams and YKK AquaGuard zips help keep wind and rain out, while the protective neckline placket adds an extra barrier where it matters most. Slanted zippered chest pockets are positioned for easy access on the go, sitting within a clean panelled design that keeps things streamlined. Finished with an elasticated toggle-cord hood, adjustable cuffs and hem, raglan sleeves for better movement, and a regular fit, it’s a functional outer layer with a reactive edge.
