Backpack in Buffalo leather. The leather has been re-tanned with vegetable extracts. Each bag is a handmade unique item that can vary slightly in color as no two hides are the same. The rugged vintage character is achieved by treating the skins with waxes and oils. Each design will get a nice patina over time. It should be noted that the wax can infect light fabrics until it dries out. FUHRHIDE cannot be held liable for stained clothing. Buffalo leather is smooth, very strong and durable. The San Miguel travel bag is handmade from 100% buffalo leather on the outside and 100% polyester on the inside. The back of the bag is breathable, giving you the necessary ventilation. We only use quality zippers from YKK. Depending on the capacity, the upper part can be rolled one or more times and attached to one of the three snap hook rings. The bag has an outside zippered pocket and wide straps for comfort. Inside, the bag has a large compartment, as well as a smaller zippered pocket. The back and wide, adjustable padded straps are made of canvas leather. San Miguel comes with a handmade dust bag. To enjoy your bag for a long time, we recommend using it for storage. Your bag is best stored in a dry place away from direct sunlight.
