MEMBRANA 3L TC: Bomber jacket made in Membrana 3L TC, a 3-layer light performance fabric made from an opaque nylon outer face laminated to a breathable, water-resistant membrane, protected by an imperceptible polyester base. STONE ISLAND's garment dyeing expertise gives an outstanding color to the outer face while preserving the performance features of the inner membrane. The addition of a special agent to the dye formula gives the piece an anti-drop finish.
