The color is khaki. This bag can be used in two ways: as a Boston bag or a backpack, depending on your needs. With a capacity of 30L, it's a good size for commuting or going to school with a bit more luggage, or for day trips to one-night trips. It's also recommended for club activities or the gym. As a Boston bag, you might have trouble putting it in a basket when riding a bicycle, but it's convenient because you can carry it as a backpack. When using it as a Boston bag, you can also store the backpack's shoulder straps properly, so they won't get in the way. It's a slightly unique design and a user-friendly item.
