This rig is great when paired with the Movi Pro Stabilizer as it transfers the weight to the hips, allowing much longer operation. The Placid helps smooth out movement in the 4th axis for smooth walking and running shots.

From the Manufacturer:
The Flowline 400N Professional Ergonomic Camera Support Vest from FLYCAM is a body-worn vest support system that is adjustable to support camera rigs weighing 17 to 22 lb. The system works by using a suspension line to support the weight of the gimbal rig, taking the load off your shoulder, neck, and arm muscles, and distributing it across your torso.

The FLYCAM Flowline Placid Two-Axis Spring Arm attaches to your Flowline camera support and provides vibration isolation to your camera, camera rig, or gimbal in two axes. Well suited to help create smooth walking or running shots, the Flowline Placid supports cameras and rigs from 11 to 44 pounds and works to help minimize both vertical and side-to-side vibration.
