Made from durable polycotton with a water repellent finish that shrugs off showers and stains, the secret to the Peter Storm Women's Ramble Lined Trousers is the brushed tricot lining that traps heat to keep you warm on cold winter days.Neat and practical, the five pockets (including a zipped security pocket) give you plenty of space to store essentials, and the articulated knees ensure a comfortable fit even when scrambling over styles.
