What is a "saddlebag"?

A saddlebag is a type of bag that is designed to be attached to a saddle on a horse or a bicycle. The bag typically has two compartments, one on each side of the saddle, and is used to carry items that are needed during a ride. Saddlebags are often made of leather, nylon, or other durable materials, and may feature buckles or straps to secure the bag to the saddle. In recent years, saddlebags have also become a popular fashion accessory, with many designers creating stylish versions that can be worn as a crossbody or shoulder bag.
