The shirt collar jacket is made of Ermenegildo Zegna's cashco (a cotton and yarn fabric). CASHCO is a family of worsted fabrics made from a special blend of cotton and cashmere. Two fibers belonging to two different seasons, two different climates, combined by Ermenegildo Zegna to create lightweight, sporty yet precious and elegant fabrics. The four pockets enhance the functionality of the garment. The fine quality of the fabric, combined with down and goose feather padding and a superlight lining, enriches the garment. The quilting and customised accessories highlight the care Eleventy puts in every detail, giving a sport-chic taste to the product.
