Stone Island Naslan Light Watro Down TC Jacket in Purple. Though quite simple looking on the surface, this jacket is actually mega complex in construction which comes as no surprise when it arrives courtesy of outerwear master Stone Island. Made from a super lightweight, abrasion-resistant fabric that boasts a resin coating - allowing the coat to be deemed mildly wind and water-resistant - it's packed tight with premium down to ensure warmth throughout winter. Externally, a coated nylon hood - complete with contrast piping - the iconic compass patch and an array of pockets complete the silhouette.
