These are a pair of flat front, button fly pants made by Magnoli Clothiers, same as his normal Indiana Jones Pants except with a flat front. Size 34W X 30.5L (outseam is 41.5"). They are Magnoli's Cashmere Wool Blend material which is a fairly tough fabric as it's his default for Indy pants. Peaked back pocket flaps, suspender buttons too. They are slightly more taupe in color than these pictures depict. $50 shipped in the US, ask for a shipping quote outside the states.
