Stone Island's Ghost Pieces are entirely monochromatic, with the theme extending even to the signature badge. The brand's latest Water Repellent Wool Ghost Piece comes in grey and is available exclusively through the Stone Island App. A natural wool shell is made with an ultra-tight compact density weave, making it windproof, breathable and water repellent. Details include diagonal pockets with zip fastening, heat sealed tapes on inner seams and Tyvek half lining with nylon mesh. The jacket is available now through March 7.
