The Eco-friendly Project Corneliani CIRCLE is the brand’s sustainable project, which writes a new chapter of the company’s history with garments only crafted from natural, organic or recycled fibres, sourced from companies and suppliers that have long embraced the sustainable revolution.. The unlined, two-button, single-breasted wool men's jacket has a classic fit and sartorial details that enhance the quality of the garment without altering its casual style. In the Circle collection, the jackets’ volume and design are revisited with an informal approach for a simpler, easier style.
