Japanese label Sacai has collaborated with American artist KAWS on a collection of cult designs that are bound to become collectors' items. From the capsule, this jacket is cut for a loose fit from camouflage-print shell and quilted with insulating padding for warmth. It opens to reveal a glossy black lining and each side is traced with a row of snap fastenings, so you can create a more A-line silhouette. Pull the drawstrings at the hem to lock in heat.
