The Fatboy Versipack has four zippered compartments with space for important travel documents such as passports or a portable CD player. The main compartment has a huge 2.6 liters of space with a tent cover that can be deployed by pulling a drawstring. Built-in are a quick release key ring, a penholder, and two integral sheaths for cellular phones, flashlights, or mace spray. Also there are two sets of nylon webbing anchors to use with our special "snap and anchor" attachment system. A two-inch wide nylon webbing shoulder strap helps distribute weight comfortably.
