Black Rapid Curve Breathe Camera Strap (replaces the RS-7): $73.95
This great strap makes it easy to carry an intermediate telephoto lens on your shoulder with a camera attached. Your rig will be pretty much instantly accessible. This new version of the RS-7 strap features lots of improvements including a breathable shoulder pad built with nylon mono mesh, curved TPE foam and poly air mesh, and adjustable length nylon webbing with buckles. It includes the (easily removed) integrated underarm stabilizer, the CR-3 connector, and the FR-5 fastener.
Important note: whenever you grab your rig be sure to give the connector a twist. Despite the fact that it is nicely designed with a locking rubber compression ring it does occasionally work loose.
