Tough Tripod Bag can be easily attached to the front panel of Manfrotto TOUGH cases through 4 metal front pins. The tripod bag can also be used as a stand alone bag through use of the included shoulder strap. Thanks to a special expandable design, the tripod bag can hold different sizes of tripods from a Manfrotto Befree series to a 055 with Xpro ball head or 3-way head attached.
