The Lowepro Pro Roller Attache X50 Case (Black) is a two-bags-in-one design that provides a rolling case combined with a removable Reserve Shoulder Bag. It is designed to carry a pro D-SLR camera without grip and attached lens, 2-4 lenses (up to a 70-200mm f/2.8) or accessories and personal items. It can also hold a laptop computer with a screen up to 14" in either bag. There are contoured and neoprene-tipped adjustable dividers that protect the contents of the bag and allows for full interior customization. The shoulder bag has a reverse opening courier-style flap to access the main camera compartment.
