The silhouette is beautiful, and it is a thin nylon zip-up shirt made of heat-resistant fiber, so it is a great item to wear lightly during times when the temperature difference between day and night is large. Since there are few helicopter crew pilots themselves, this kind of real military vintage is naturally rare.
