Drapers' Ascot 4-Ply is one of our favourite high-twist fabrics for custom trousers. At 370 grams, it is slightly heavier than most tropical worsteds, yet its open weave ensures it remains breathable for summer wear. Durable and crease-resistant with a subtle texture, it combines airy comfort with the elegant drape and structure afforded by its weight. This light grey version is practical and versatile, pairing seamlessly with a variety of sport coats in navy and brown tones.
