A casual Dulles bag from the “Bump” series, featuring a simple appearance combined with various functional details and excellent storage capacity. This model updates the main body material to waterproof leather.

Product Description

The main material uses carefully selected domestic steer leather that has been chrome-tanned and infused with a 3M water-repellent agent during the dyeing process, allowing it to penetrate deep into the leather fibers. It provides long-lasting protection against water intrusion—not only on the surface, back, and edges of the leather, but even from scratches.

This leather has passed the monitoring tests of 3M’s “SCOTCHGARD®” for water and stain resistance. The testing is conducted even after the surface is abraded, ensuring the effect does not easily diminish.

Using relatively lightweight and soft domestic raw hides, the leather is tanned with an emphasis on lightness and suppleness. Finished in semi-aniline, it features a delicate surface touch and achieves a fine-grained, smooth texture similar to kip leather.

The top of the bag features a Dulles lock that allows one-touch opening and closing. It can also be secured with the included key.

The original master-piece hook buckle allows you to hang lightweight items for added convenience.

The shoulder harness is equipped with the original “m-strap” (utility model registered) mechanism, designed to reduce the load on the body when carrying.

The storage compartment includes dedicated spaces for a laptop or tablet, as well as thoughtfully arranged pockets. The divider inside the main compartment is removable and adjustable depending on the size of your belongings.

*This product is available exclusively at the master-piece ONLINE STORE and directly managed retail stores.

Attention

The metal frame may deform if subjected to strong impact or excessive force. Wrinkles from the dyeing and coating process may appear uneven or streak-like.

This product is not completely waterproof. Water may penetrate through stitching holes or seams.

If the attached nylon material is left wet for a long time, the backing film may peel off or deteriorate. Please dry thoroughly before storage.

The water-repellent finish is applied to the surface and may gradually diminish due to friction or dirt accumulation.

Although a highly durable PU coating is applied, it may peel if rubbed against hard objects.

The attached leather may show natural wrinkles and scratches unique to each hide. Please note that color transfer or fading may occur due to friction.

As this is natural leather, exposure to rain or water may cause staining.

Product specifications are subject to change without prior notice.
