Zegna crafts this black sweatshirt from luxurious mulberry silk, blending fluid drape with structured tailoring. The design defines itself through a Korean-style collar, half-placket closure with braided buttons, and button cuffs, creating a hybrid silhouette that elevates the everyday layer. Ribbed hems ground the silhouette with proportions recalling structured outerwear. A tonal leather brand mark at the back provides discreet signature detailing.
