Flexible black denim where you move, structured grey denim where it holds. Give and shape in the same pair.

Reinforced where pants blow out
Double-layer seat and knees. The first place most pants fail. The last place these will.

Elastic ankle cuffs. Tight for the wall, loose for the street. Your call.
