The Dell Professional Backpack 15 securely stores your 15" laptop and tablet within a dedicated plush lined laptop compartment and tablet pocket while you're out and about. Multiple storage compartments organize and protect your everyday office essentials. Water resistant and durable materials protect your laptop and accessories from the weather while reflective accents on the bag provide increased visibility during low light commute hours. Carry the backpack in three comfortable ways using the padded handle grab, adjustable padded shoulder straps, or the trolley pass-through for attaching to rolling luggage. You can also charge your laptop within the bag on-the-go with a portable battery charger (sold separately) tucked neatly in the dedicated battery pocket via a cable pass-through.
