It's sweater weather (and it probably will be for a while). You pretty much can't go wrong with one made from lambswool: It's soft, warm and always a good decision when the temperature starts to drop. This half-zip has an eye-catching Fair Isle pattern (named after one of the Shetland Islands). 100% lambswool. Dry clean. Blue and white Fits true to size Men's small New with tags - current season at J. Crew!
