These appear to be casual linen-style pants with an elastic waistband and visible patch pocket. The material and relaxed style suggest 'Chinos & Khakis' is not right; they are not sweatpants/joggers (no cuff), not dress, not corduroy, and not cargo (no multiple large utility pockets). Best fit: 'None' of the listed categories perfectly match, but closest is 'Chinos & Khakis'.
