Stone Island Jacket Maroon Tank Shield. Heading into the winter months, waterproof / breathable jackets are in-demand. Using the exclusive Tank Shield fabric, Stone Island have achieved such a jacket including multi layer fusion technology. The garment is firstly made in opaque polyester tela then laminated with panels that slightly overlap and cover the inner surface of the garment. This creates a shield for the outer fabric and seams whilst the multi layer fusion guarantees improved waterproofness and breathability. An inner removable down filled lining gives the jacket that added functionality for the colder months.
