Our Lancaster bomber jacket is smooth like butter. That's largely due to its soft, buttery hand-feel (made of 95% cotton 5% cashmere). Yet ribbed cuff detailing, interior breast pockets and a printed lining make it extra smooth. Everything's better with butter. The Lancaster features a zipped closure and is also available in sage. Made from 95% cotton and 5% cashmere. It features prints, ribbed detailing and a zip closure. Machine wash and tumble dry low.
