Color and Material: The bag is made of a dark grey, durable fabric, likely ballistic nylon or a high-quality synthetic material, giving it a professional yet rugged appearance.
Convertible Design: This bag can be carried in multiple ways:
Backpack Mode: The back panel features padded shoulder straps and potentially a top handle for use as a traditional backpack.
Briefcase Mode: The shoulder straps can be tucked away into a back panel, allowing the bag to be carried by the handles on the side. The first and third images highlight this feature.
