Wondlan's showing off some type of 'wearable support' (shown above) that can be used to unload the weight from camera stabilizers like the Wondlan Ares (Merlin-like). Seems like the same idea Glidecam has with their Body-Pod.
Glidecam Body Pod for Hand-Held Stabilizer
But unlike Glidecam's Body Pod, Wondlan shows how it can be used to support a shoulder rigs as well. In that case, it sort of reminds me of the Tiffen (Davis & Sanford) Steady Stick.
IMO, the price is too high for something that doesn't come with a professional padded belt and strap. The images and descriptions aren't very clear either on how it all connects together. From this end it just looks like an adjustable stick on a belt.
