Our Large Exterior Pockets are perfect for carrying your laptop without taking up interior space in your bag. The Rollerboard option attaches an adjustable wide band of leather across the back width of your bag, for easily sliding over the handle of your rolling suitcase - convenient and arms-free carry for travelers. The Newspaper Pocket adds a large divider to the outside width of your bag, perfect for stashing your itinerary, file folders or, you guessed it, your daily newspaper. The Backpack Option adds D-rings to your bag for attaching backpack straps with swivel snaps - great for frequent travels or bike commuters. The Pro-Series strap upgrade takes you from the standard 1" strap offered with this Satchel, to a 1.5" beefier strap with an adjustable shoulder pad. Tie Down Straps can be used to secure the Satchel to a vehicle, or to secure smaller items to your Satchel.
