At a capacity of 45 liters, the TB-621 Arsenal duffle bag is large enough to be used as luggage. Transporting this pack can be done by using the top carry handle, the removable over-the-shoulder strap, or it can be worn as a backpack when loaded down with everything needed for 72+ hrs. The TB-621 Duffle Pack boasts a large main compartment containing two optional-use collapsible dividers as well as two quick-release gear straps for securing larger items. Two internal soft-lined pockets provide storage for valuables or smaller items. The entire duffle pack is clad in MOLLE webbing for the addition of gear and/or pouches.
