These are OD-colored field trousers made from 18-ounce twill wool serge material adopted by the US Army in 1951. Designed for use in cold regions, these trousers were used in temperatures down to -10 degrees Celsius. When temperatures dropped below -10 degrees Celsius, Arctic overpants with liners were used. With no pleats and a generous thigh, these trousers are full of the classic charm of the 1950s. Their simple, high-quality construction is sure to satisfy those who appreciate the difference! The front features a zipper fly, a characteristic of the later models, and a single back pocket. They also have easy-to-use side slash pockets and one button-closure back pocket. The shape is similar to chinos, with a straight, wide silhouette. These are USED but in very good condition. They can still be worn for a long time. Please understand that these are used items before purchasing. Size: Waist (flat): 43 cm Hem width: 19 cm Inseam: 78 cm *Please note that these measurements are approximate.
