This garment type, characterized by its two layers, typically combines an outer shell of durable, weather-resistant material like nylon or leather with an inner lining for warmth, often made of shearling, wool, or synthetic insulation. A classic example would be a leather bomber jacket with a detachable shearling collar and lining.
The dual-layered design provides significant advantages in terms of versatility and protection against the elements. Historically, such jackets were crucial for pilots operating in open cockpits at high altitudes, offering both warmth and wind resistance. This functional heritage contributes to the enduring popularity of this style, which has transitioned from a purely utilitarian garment to a fashion staple. The adaptable nature of these jackets allows for comfortable wear across a range of temperatures and weather conditions, making them a practical and stylish choice.
