The piece is made from polyester, a fabric that suits its retro aesthetic and casual, everyday wear. The material supports the structured flat-top and curved-brim shape while remaining foldable for easy storage, and its medium thickness and breathability make it a practical choice across all four seasons. The houndstooth pattern and embroidered crest detailing sit cleanly on the polyester surface, giving the piece its old-money-inspired, understated look for daily use.
