These black Haider Ackermann 'Biker' straight-leg trousers add a rebellious edge to your outfit on those days when you have to show face at a function even if you would much rather be burning some rubber on your Ducati. The iconic biker style trouser is crafted not from traditional leather but instead a black cotton and spandex blend fabric and has a mid-rise waist, concealed zip pockets at the front, straight leg fit, regular cut on the leg and trademark panelled construction and stitch detail on each knee. Wear your Haider Ackermann trousers with Rick Owens and Lot78.
