This is a shoulder bag made of black suede material. It has an adjustable strap. This DOCUMENT BAG uses waterproofed WATERPROOF pigskin and a water-resistant zipper, making it resistant to rain and dust. MASSTARD's standard pigskin, which is very light and has excellent abrasion resistance and tensile strength, has been specially processed to withstand all weather conditions, pushing it to new heights. It's simple and easy to use, and the silhouette looks beautiful regardless of the amount of items you put inside. Because of its waterproofness, you can easily carry items that are sensitive to water, such as documents, tablets, and computers. Those who use MASSTARD's helmet bags probably understand the quality of pig leather, but the good thing about this DOCUMENT BAG is that the items inside are "won't fall out, won't get wet, and won't get dirty." Furthermore, the length of the shoulder belt can be easily adjusted with a buckle, making it versatile and suitable for various usage environments and fashions. When riding a motorcycle or bicycle, you can shorten it to the maximum for a messenger bag style. Even when used in the city, it drapes beautifully and conforms to the body, even when worn over thick clothing like coats and blousons, adding an accent to the heavy atmosphere of autumn and winter. It also has considerable storage capacity, so it's suitable for a one-night, two-day trip. Please try the new DOCUMENT BAG proposed by MASSTARD, which is light, stylish, and also has functional beauty.
