The Dell Professional Backpack 15 securely stores your 15" laptop & tablet within a dedicated plush lined laptop compartment & tablet pocket while you're out & about. Multiple storage compartments organize & protect your everyday office essentials. Water resistant & durable materials protect your laptop & 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.
