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. You might have trouble with a Boston bag fitting in a bicycle basket, but this bag can be carried as a backpack, which is convenient. When using it as a Boston bag, you can neatly store the backpack shoulder straps so they won't get in the way. It's a slightly unique design and a very user-friendly item.
