The Panama work pants are distinguished by Stone Island’s ‘OLD effect’ — a garment‑dyeing treatment that gives the fabric a deliberately aged, lived‑in appearance. Made from durable Panama cotton, the process softens the fibres and creates subtle patina across the surface, echoing the brand’s fascination with time and transformation. 100% Cotton Button & Zip Closure 2 Hand Pockets 2 Rear Pockets Stone Island Badge on Leg Style Code: L1S153100037-V0120 This product has undergone a special dyeing process.
