Putting the ultra in high-viz, Vollebak’s Blue Morpho winter sport jacket utilises no fewer than two billion microscopic glass spheres in its unique performance shell to create a ridiculously reflective jacket that changes colour depending on the available light, transforming from a liquid metal lustre in direct sunlight to a bionic blue come nightfall. Inspired by the iridescent wings of the Blue Morpho butterfly, the soft-touch jacket is engineered for enhanced movement with ample room for layering over a hoodie. It’s also fully seam-sealed and waterproof, with an ocean-racing-style hood and high collar to keep out the elements.
