Stone Island Formula Steel Insulate Jacket from AW1995. During the final period of legendary Osti. The Formula Steel is one of the experimental coated synthetic fabrics associated with Stone Island’s 90’s material research. Polyurethane coating is the coating is responsible for the unusual metallic, almost oxidised-looking surface. With age and wear, these jackets develop shifts in sheen and colour rather than looking like a conventional flat nylon jacket. A proper jacket with character.
