Stone Island's UV-Reactive Chain Stitch Sweater

Stone Island UV-Reactive Chain Stitch Sweater

Stone Island expands its legacy of material innovation with the use of UV-reactive fabric for Spring/Summer 2025.

Known for pioneering textile technologies, such as their signature thermo-sensitive pieces, Stone Island continues to push boundaries with a sun-activated sweater that merges refined craftsmanship with experimental design.

Now available in-stores, online and on the HAVEN app.

UV-Reactive Yarn

Constructed from a dense rayon-nylon rope yarn, this knit is engineered with innovative UV-reactive pigments that respond to sunlight. Under indoor lighting, the garment retains a neutral tone, but once exposed to UV rays, the embedded pigments activate, shifting the yarn to a vivid Cherry hue.

Built to Last

Hand-knit with a coarse 1.5-gauge rayon-nylon cord, the sweater features bold chain stitching and a ribbed mock neck, enhancing its relaxed silhouette and ease of layering. Finished with the iconic Rose des Vents badge on the left sleeve, it seamlessly combines craftsmanship with a laid-back, contemporary aesthetic.
