This modern take on the sweater-jacket gets a luxe upgrade in merino wool. Merino is a great transitional wool — lightweight, smooth, refined and perfect for layering. It also means this sweater is light enough to toss over a tee or Oxford cloth shirt now, and then layer under a coat or suit jacket when the weather turns chilly. Design details include fully-fashioned arm holes, a 2-way metal zipper with the TS logo and two layers of wool at the neck (so it holds its shape).
