Stone Island really knows its stuff when it comes to highly technical outerwear. This coat is made from a garment-dyed cotton-blend that's treated for resilience (a technique the brand has advanced significantly) and has a fuzzy shearling-lined hood to keep you cosy. Designed for a generous fit, it's fully lined and filled with lightweight insulating down, while the zip, button and snap fastenings ensure you're protected from the wind. Store your phone, wallet and gloves in the four front pockets.
