The wool & linen fabric is perfect for 3 seasons (Spring, Summer, Fall) although our clients in places like California and Florida live in this cloth year-round. The fabric, milled in Italy by Vitale Barberis, is a blend of premium linen (57%) and tropical wool (43%) which makes for an extremely versatile garment that is a joy to wear. At a perfect 9oz/255g, you get the breathability, texture and charm of linen with the durability and performance of wool. This one is sure to bring your Spring/Summer wardrobe to a whole new level.
