That's not a typo, folks. The box says b-grip and there are no capital letters. Never mind the graphics, however - the product is excellent.
In the past few years there have been a plethora of camera carriage systems that suspend camera bodies from various parts of photographer's bodies. I've seen chest mounts, waist mounts, and dragoon strap mounts. There have been mounts for knapsack slings and Sam Browne belts. Padded neckstraps with extra cushion straps and under-the-arm secret agent styles.
But in many cases they forget that once a heavy lens is mounted, the camera gear takes on a whole new physics - Quite frankly some of these rigs have a mind of their own. You go east and they go west - or worse, set up a pendulum action.
b-grip have recognized this and made a waistbelt system that is designed to actually control a camera with a zoom lens. Look at the picture of the basic platform - see the long base under the front of the camera platform? That sits against the leg when the camera and lens are depended from the belt and stops the gear from rotating away from the vertical. This is particularly useful if the hotshoe of your camera has a flash and a Lightsphere II diffuser mounted on it - AKA wedding tackle. If you need to tie the rig to the leg, like a pistol holster, there are two anchor points moulded into the bottom of it. Strap that sucker down...
You can lock the quick release plate onto this platform so that it doesn't jump out, and you can also purchase a standard tripod mount to take that quick release plate - a complete system for the operator to hop from tripod to hand to belt.
Have a look at the swing-out foot that comes forward from the quick-release plate - this has been designed to allow you to place the whole assembly down on a tabletop for selfies. Neat, eh?
As well, they have made up a similarly-configured side strap that you can mount on your camera for the quick-draw sort of wedding shot. I wonder if they spent some time watching spaghetti westerns...
None of this is expensive - $ 79.95 for the basic waistbelt and platform - $ 49.95 for the handstrap system.
That's just a fistful of dollars....You can be good, or bad, or....
