The piece is built from a main fabric of 56.44% cotton and 43.56% polyester, with a 420g weight that gives it a substantial, structured feel suited to the armored, utility-inspired look and to regular wear through autumn and winter. The cotton-polyester blend supports the washed, distressed finish and the faded, weathered color effect, while the weight and standard fit make it appropriate for casual layering in colder weather. Inside, the lining is 100% cotton at 200g, a breathable natural-fiber interior against the body. Together the two components keep the piece comfortable for everyday casual wear while maintaining the structured silhouette of the design.
