Rigid cotton denim with minimal stretch, which is what lets it hold the loose, straight drop through the leg instead of clinging — expect it to soften and mold to your fit gradually with wear. Machine wash cold inside out to protect the khaki-toned fade, and hang dry to prevent shrinkage that would shorten the deliberately long, floor-grazing leg. Because there's little stretch recovery to rely on, sizing is worth checking carefully against your measurements rather than the fabric, since a rigid denim like this won't flex to make up for a snug fit. With repeated wear the denim will crease and soften at the knee and hip in a way that reads as authentically broken-in rather than worn out.
