This is Manfrotto’s largest and finest padded tripod case, intended for the 161MK2B tripod. But it is also a perfect fit with the Oberwerk TR3 Tripod that is included with the Oberwerk 25/40×100 and BT-100-45. Zipper extends down the length of the case, but also fully opens the top at the case. High-quality durable ballistic nylon exterior, with Thermofoam padding which holds the tripod in place and protects it during transport. Inner pocket holds accessories (such as video head pan bars). Can be hand-carried horizontally with the side handles, vertically by the end handle, or shoulder-carried using the included shoulder strap. Exterior length is 46″.
