Leyden and Sons Leather Bag Co. - Roosevelt Saddlebag 100% Leather (4 - 5 oz) Suede lining As leather is a natural product, there will be a certain amount of natural wear. It will scuff, crease, and maybe even crack, but we like to think of this as the bag getting to know its new owner. To keep it healthy, we recommend conditioning the leather every few months, but the frequency of application will largely depend on the amount of use and climate. Becomes a backpack with just a few clicks of the strap! We only use the finest single-ply, boot-grade leather, carefully constructed for quality that lasts. Suede front-flap lining for a softer, more attractive interior.
