In creating the Golden Fleece® Collection, we sought out the world’s finest raw materials and innovative technologies to craft garments that meet the highest standards of Brooks Brothers. This button vest is made from extremely fine Loro Piana® merino wool and was knit by our sweater masters in Italy. As part of our 3-D Knit Collection, it has been fashioned as a single, continuous garment, rather than assembled in panels. Without seams, it offers an improved fit, greater comfort and increased durability. Features real mother-of-pearl buttons. Dry-clean only; made in Italy.
